INDIANAPOLIS -- The Indianapolis Colts enjoyed a perfect bye weekend.Players spent time with their families. They got a chance to relax a bit and ponder this seasons final sprint.Now its time to get back to work -- and back in the playoff hunt.We have to win, safety Mike Adams said Monday. You look around the league and playoff football has already started. So we have to do what we have to do to win.It sure hasnt been easy to do that this season.The Colts (4-5) still havent won consecutive games, have dealt with myriad injuries and have heard a drumbeat of criticism over their repeated mistakes.Indys surprising victory at Green Bay to open November changed everything. Before heading home, players looked at ease, coach Chuck Pagano was smiling and everyone was eager to begin their final seven-game sprint to the finish.When they returned to the team complex Monday, everyone was still upbeat.It was a great opportunity for guys to get away, to let their bodies heal, to mentally refresh, tight end Dwayne Allen said. Weve been at it since July 26 or something and thats a long time. So we needed the break.Of course, the first order of business after returning was checking in with team doctors.Pagano did not address reporters Monday, but what happened on the practice field spoke volumes about the health of the team. Left guard Jack Mewhort (triceps) and defensive tackle Henry Anderson (knee) returned to practice after both missed the past three games. Right tackle Joe Reitz was wearing a non-contact jersey as he continues to progress through the concussion protocol.Now the Colts are onto their next opponent, Tennessee (5-5). The Titans have won two in a row and can put themselves in solid playoff position by snapping a 10-game losing streak to Indianapolis and winning for the first time at Lucas Oil Stadium.The rejuvenated Colts have other ideas, especially now that they seem to have some momentum.Its real important, receiver Phillip Dorsett said of the new attitude. That momentum can take guys far.Nobody in the locker room expects a few days off to be a cure-all.Indy understands it must reduce the penalties and sacks and find ways to keep the offense on the field and the defense off it. The Colts also realize that to get back in the postseason chase they must start playing more consistently in all phases.If they do all that, perhaps they can take advantage of a schedule that looks softer now than it has all season. Their three remaining division games are all at home and they face only three teams with winning records -- Houston (6-3), Minnesota (5-4) and Oakland (7-2).Put together a winning streak and the Colts could claw their way back into the mix for a third division title in four years -- and possibly avoid missing the playoffs in back-to-back years for the first time since 1997 and 1998.But they cant afford to regress any more.Instead, they must find a way to build off the momentum they had last week and fix their flaws.Weve got to win, Adams said. We cant this have roller coaster stuff going on. We had time to regroup, time to get this consistency out of here and weve got to believe we can do it.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFL Wes Martin Womens Jersey . -- The Sacramento Kings are set to become the first major professional sports franchise to accept Bitcoin virtual currency for ticket and merchandise purchases.

RIO DE JANEIRO -- Helicopters were up at daybreak spotting rubbish flows at the Olympic sailing venue, with boats below collecting the debris.Dozens of barricades dammed up streams that flushed garbage into the bay. They caught waterlogged sofas, Styrofoam cups and deflated soccer balls.A sewer pipe at Marina da Gloria stopped raw sewage from being pumped into the harbor where Olympic boats were moored.Rio de Janeiros water remains filthy as the Olympics wrap up, even after a final push to clean up the water for the worlds largest sporting event. Fans were reminded by the stench from a lagoon contaminated with raw sewage that abuts the Olympic Park.Long after the athletes and fans leave, the city will continue to struggle with water teeming with bacteria and viruses.Rio organizers promised in their 2009 bid document that the Olympics would drive a cleanup of Rios waters, pledging to treat 80 percent of the waste. Estimates vary, but most suggest the area is still treating less than 50 percent of its sewage.For two weeks, Olympic athletes competing in the water largely avoided falling ill by building immunity to pathogens, using preventive measures, or by trying to limit contact with the water in water-based sports.An independent study by The Associated Press conducted at sites around the city over more than a year -- including the sailing venue in Guanabara Bay and the rowing venue in Rodrigo de Freitas lagoon -- showed dangerously high levels of contamination.In over 16 months of testing leading up to the games, there was no decline in the very high bacterial and viral levels in the water, underscoring that the cosmetic measures authorities took to make venues appear cleaner ultimately didnt reduce the risks.The contamination is always there, and the sad thing is that its not going away any time soon, said Dr. Fernando Spilki, the Brazilian virologist and coordinator of the molecular microbiology laboratory at Feevale University in southern Brazil, who was commissioned by AP to conduct the water tests.Falling ill depends on a variety of factors.The majority get infected, a few get sick and adults normally (have built up) some immunity, Spilki added.It is difficult to link symptoms to Rios water because many gastrointestinal illnesses can be blamed on things like simple travelers diarrhea, and some symptoms may not show up immediately.That could make it hard for anyone looking to blame the water for illnesses that emerge when they go home. Dr. Nebojsa Nikolic, medical director of World Sailing, attempted to trrack sailing illness during a test event a year ago in Rio.ddddddddddddHe concluded that the frequency of illness was not unusual, but also said the exact causes could not be determined without human stool samples of sailors in dozens of countries.Nikolic said hell conduct a follow-up study of the Olympics.From what we know there were only a few cases scattered across different teams without influencing the sailing performance, Nikolic said in an email.Sailors and rowers said the water appeared cleaner than it was a year ago, the result of numerous stop-gap measures employed by the Brazilian government. Most of it focused on corralling floating trash, but officials also deployed bioremediation efforts during test events, but declined to specify exactly what it entailed.We had taken precautions just in case, because the water quality last year and the year before probably wasnt that good, said Lisa Carrington of New Zealand, who won gold in womens 200-meter singles. But I feel that the water here today, this week, is really good.Precautions taken by athletes across polluted venues included keeping water bottles in plastic bags, bleaching oars or paddles, using hand sanitizers, and washing clothes immediately after practicing or racing.Brazilian canoeist Isaquias Queiroz said hes trained in Rio for two years and noticed the water is much cleaner.I even wondered if they had some kind of chemical product in it, he said.Andy Hunt, the CEO of the governing body World Sailing, said Belgian Evi Van Acker was the only sailor he knew of who fell ill during the games. Her coach said it was due to an intestinal infection she contracted while training in Rio last month.World Sailing gave extensive hygiene guidance beginning a year ago after sailors fell ill in Rio at a test event.Everyone has been very careful in using hand hygiene, washing down clothing, boats and so on, Hunt said.Dorian van Rijsselberghe of the Netherlands, who won gold in mens windsurfing, criticized Brazilians for not keeping their promise to thoroughly clean the bay.Not everything is OK, Van Rijsselberghe said. Thats the thing. Brazil made a promise a couple of years ago and they couldnt keep their promise.---AP reporters Karl Ritter, Bernie Wilson, and Peter Prengaman contributed to this report.---Stephen Wade on Twitter: http://twitter.com/StephenWadeAP .His work can be found at http://bigstory.ap.org/content/stephen-wade ' ' '
