Sidney Crosby collided with a Pittsburgh Penguins teammate last Friday at practice and thought nothing of it. Just one of those things.When the two-time MVP woke up Saturday, though, the headache he experienced felt familiar and he was hardly surprised by the concussion diagnosis that will keep the Penguins captain out indefinitely.Its well-worn territory to be sure for a player who missed the better parts of two seasons following a blindside hit to the head in January 2011.That doesnt mean, however, that what Crosbys dealing with now will linger as long -- or as frustratingly -- as those interminable two years when he wondered when hed get right.If anything, what he endured then will only help him going forward.I think going through it, you understand the process and I think that progress is a good thing, he said.Crosby felt good enough on Tuesday to spend nearly an hour on the ice skating alongside injured teammates Bryan Rust and Matt Murray, but he declined to set any sort of timeline on when he may return.Call it the residue from the aftermath of the hit by Washingtons David Steckel during the 2011 Winter Classic that forced Crosby to hit pause on his spectacular career.I just go day by day, Crosby said. You dont look too far ahead.Both Crosby and the team declined to get into specifics about what exactly happened, though he insisted the injury is a result of getting tangled with a teammate at practice and not something that occurred during the recently completed World Cup of Hockey. Crosby was the tournaments MVP after leading Canada to gold.Im not making this up, Crosby said. It was pretty clear I think.Crosby will remain in the concussion protocol for now, a series of procedures he knows well, ones that continue to evolve as more research comes to light.Weve learned so much in a short period of time, Crosby said. I think theres a really good structure in place on how to get back and that kind of thing. I feel confident and comfortable with everything.The Penguins open the season Thursday night at home against Washington and during a pregame ceremony will raise the banner for the franchises fourth Stanley Cup title. Crosby almost certainly will be out of the lineup, but he harbors no concerns about how this latest head injury will affect him in the long term.(Concussions) happen, he said. They happen in a lot of different sports and guys have multiple concussions and theyre fine. Just have to treat them the right way and make sure they handle it right and youre honest. Like I said, Im comfortable and confident that things will be OK.The timing is eerie when it comes to the level of Crosbys play. He was leading the NHL in scoring and in the middle of perhaps the best hockey of his career in 2011. This time, hes coming off a stretch in which he captured the Conn Smythe Trophy as the playoff MVP while leading the Penguins to a title and backed it up with a sublime performance in the World Cup.Thats the first thing I thought when I saw the headline, said Buffalo Sabres coach Dan Bylsma, who coached Crosby in Pittsburgh from 2009-14. Id like to compete against him and beat him, no question. But at the same time, I hope hes able to get back to playing, and get back to playing the way he can.Crosby, a notorious workaholic, needs hockey. Theres little doubt the NHL needs him.You want the top players in the game, said Washington Capitals defenseman Matt Niskanen, a former teammate in Pittsburgh. Thats best for everybody. When everyones best players are in the game, thats what everyone wants to see. But most importantly for the individual, you just hope that its nothing serious.The Penguins have been able to survive without Crosby in the lineup, at least during the regular season. Evgeni Malkin won the Hart Trophy (MVP) and the Art Ross Trophy (leading scorer) after the 2011-12 season, a year in which Crosby was limited to 22 games as he continued to battle concussion-like symptoms.We know how we can play better with Sid, but we can play better without him, too, Malkin said. We have great teammates and great leadership group here.And a core that is only too aware of the toll concussions can take. Defenseman Kris Letang has dealt with multiple concussions during his career, and goaltender Marc-Andre Fleury suffered one late in the regular season that kept him out so long his job was eventually taken by rookie Matt Murray, who helped guide the Penguins to the Cup.As encouraging as it was to see Crosby in the dressing room on Tuesday, the Penguins are taking nothing for granted.It makes your mind think maybe hes close, but these types of things are on their own timeline and no one compares to somebody else, forward Chris Kunitz said. The good thing is he understands what hes going through, and hell be the best one to be able to come back from it.Game notes The Penguins claimed goaltender Mike Condon off waivers on Tuesday and assigned Tristan Jarry to their AHL affiliate. Condon will back up Fleury while Murray recovers from a broken hand.---AP Hockey Writers Stephen Whyno in Washington and John Wawrow in Buffalo, New York, contributed to this report.

Nike Sb Shoes For Sale .Y. -- Sabres forward Drew Stafford has witnessed plenty of turmoil during his eight seasons in Buffalo. So the Rajkot Test, the Indian teams first, wary embrace of regular DRS has passed without what the police refer to as untoward incidents. Cheteshwar Pujara will offer us his thoughts about DRS at a later date, no doubt - about his very smart referral in the first innings, which got him past a dream home Test century.We must realise that Rajkot, of course, has not quite marked the beginning of a beautiful friendship: the DRS is on trial all through the series against England. We can only hope that by the time it is done, this prickly relationship will be free of the old hang-ups, and that the Indian team will join the rest of the cricket world in using the DRS as standard practice.Virat Kohlis men belong to a generation younger to that of the DRS-scarred class of 2008. To be fair, even that lot would probably have given the DRS a shot outside of ICC events at some point had the system not found itself trapped in front with an identity crisis: What am I? What have I become? A broadcasters add-on? A regulatory requirement? A political tool for the powerful in a sulk?In 2016, things are clearer. The DRS is a regulatory requirement that is a few steps closer to being under the ICCs full control. The eventual intention is for it to be consistently applied in the international game. For the first time, Zimbabwe too used a version of the DRS in a home Test versus Sri Lanka last week. It was DRS lite - with ball-tracking, sans stump mic - but no one was complaining.Indias reservations over the DRS have been quelled for the moment due to several factors. Like improvements in the quality of the replay footage used by the Hawk-Eye tool - from 75 frames per second in 2011, we now have 340, which provides more data to predict the path of the ball.Also, there has been the addition of Ultra Edge technology, which was introduced at the start of the year in the South Africa v England series. This combined sound-based edge detection with simultaneous camera frames to help pick up finer edges, added a new component to the information available to the umpires. Taken together, these made for a sustained push for the argument in favour of the DRS.What added an extra layer of persuasion was the decision to take the DRS out of the cricket broadcasting environment and into a neutral laboratory. Anil Kumble, the head of the ICCs cricket committee, and Geoff Allardice, the ICCs general manager, leaned on science to ask questions of the technology tools at hand and to set up new parameters for DRS technologies of the future.Kumble, captain of India in that 2008 DRS-disaster series, tackled the project not as a cricketer who had a bone to pick with technology. It was studied as a mechanical-engineering problem that required a mechanical-engineering approach as a solution. Good thing Kumble, currently the India coach, has a degree in the subject.The exercise began in September 2014 with a set of meetings between Kumble, Allardice and Massachusetts Institute of Technology (MIT) engineers in Boston. Sanjay Sarma, MIT professor of Mechanical Engineering says, Accuracy is a key question that any engineering task asks about measurement technologies. How precise is it? How repeatable is it? Has this been characterised? Anil Kumble and Geoff Allardice came to us with these questions.A cricket fan, Sarma had his own mixed feelings about the DRS. On the one hand, I do believe in reviews, in technology, and in the visual benefits of DRS. On the other hand, I didnt know if and how DRS was being calibrated.The DRS had more than an identity crisis; rather, it came with a built-in structural flaw. Given that analogies about parachutes and safety equipment have been used in the context of the DRS in the past, here is another. Lets compare it to a house constructed without a blueprint and assembled on the go with a variety of materials added on randomly. Going to MIT and getting DRS technologies tested independently was like asking an architect to check if the doors in a house already built would always shut correctly and that the roof wouldnt possibly collapse. What MIT did was invent the equipment that would answer those questions and also give the ICC clear technology parameters for the use of DRS in future. The September 2014 meetings marked the beginnings of a year-long project, which involved Sarmaa, Dr Jaco Pretorius of South Africa, and Stephen Ho, an American research scientist at MIT.dddddddddddd While Sarma and Pretorius were from cricket-playing nations, Ho, like the students involved as consultants in the research, had no knowledge of the sport. Sarma says, They all found the sport quaint, but over time have started playing gully cricket in our lab retreats and in the hall at MIT.Two US engineering firms, Mide and Bell-Everman, constructed the equipment, the Swinging Arm that tests the Real Time Snicko/Ultra Edge, and the Frame, which studies the ball-tracker. Two sets of tests were conducted using these tools, the first in a closed environment, like at Loughborough University last year and the other in a real match environment. Ultra Edge for example was tested behind the scenes with no public notice during the September 2015 England v Australia ODI at Lords.RTS and HotSpot, which are owned by BBG Sports, one of two cricket technology providers along with Hawk Eye, went through their offline testing at a suburban ground in Melbourne in April 2016. This was two months after being observed at work during the New Zealand v Australia Test in Christchurch. HawkEye was put to the offline MIT-ICC tests in April 2016 in Winchester, UK and then observed a month later during the England v Sri Lanka Test in Durham. The only other ball tracking technology available to cricket, Virtual Eye of New Zealand will be tested in February 2017 towards the end of the southern-hemisphere season.The equipment used to test the DRS now sits locked up in crates that are in the ICCs possession in Dubai. The MIT team, Sarma says, has recommended that the tools used in the DRS are characterised/ qualified periodically, i.e. tested to check if the parameters arrived at earlier still hold true. During the course of the project, the impact of physical conditions on the DRS tools, like wind on the speed of sound, for example, was also studied but found to be small in relative terms, or easily tackled.The ICC now owns a proper blueprint with which to build and add to their DRS house. The chief executives meetings in February will possibly involve discussion about what could be the next series of issues to be tackled on the way to a consistently applied DRS, with mandatory tools like the ball tracker and sound-based edge-detection systems. Cost would definitely be one: a five-year-old estimate says a basic DRS system costs US$5000 per day; that figure would be higher today, with far more sophisticated technologies involved. Apart from the monies, the fact that the DRS package will be owned and controlled by the ICC raises even more questions.If the ICC does take full control of the DRS from broadcasters, it has to decide in which matches the system is to be used. All formats? All formats across mens and womens cricket? How can the logistics involved be brought in sync with the current cricket calendar? Given that in every match that features the DRS, the ICC appoints its own DRS-trained third umpire along with the two on-field umpires, how many more ICC-approved third umpires would need to be DRS-trained and sent out to work matches? That is in the future and outside the ambit of the systems most reluctant followers.For the Indian team, though, there is one element of the DRS that will prove challenging, but which cannot be fixed by machines or scientific tests. It is to do with how the technology is used by the players in the middle, and here the Indians will have to catch up quick.In Rajkot, Pujara experienced all sides. After his inspired first-innings referral, in the second he walked off glumly, leg-before to one from Adil Rashid that pitched outside leg. At the other end, M Vijay had respectfully turned his back to the departure, without alerting his partner to the possibility of a review. It was, no doubt, an instinctive response, born of a DRS-free Test match habit. It led Sachin Tendulkar to say that the third umpire needs to intervene in such instances. Lets not get into that now or we will be here for another eight years.Yes, the umpires decision must be respected, but in the Indian Test teams new world, sometimes, the old rules dont apply. ' ' '
