SANTA CLARA, Calif. -- On Monday, NFL agent Drew Rosenhaus appeared at the San Francisco 49ers second training camp practice. Afterward, he and client NaVorro Bowman, the teams star linebacker, were seen walking upstairs to the offices that rise above the practice fields.By Wednesday night, Bowman and the 49ers had agreed to a four-year contract extension, which will be added to the three years Bowman had remaining on his previous contract. Sources told ESPN NFL Insider Adam Schefter that the four-year extension is worth $44 million, including $20 million guaranteed.Bowmans new-look pact takes him through the 2022 season and solidifies his standing as a franchise centerpiece for coach Chip Kelly and general manager Trent Baalke.At 28, Bowman is coming off a bounce-back 2015 season in which he overcame a devastating knee injury, which cost him the entire 2014 season, and earned his fourth first-team All-Pro honors. By his own admission, Bowman wasnt at full strength in 2015, but he managed to lead the NFL in tackles, with 154 to go with 2.5 sacks and a forced fumble.Entering this season, Bowman made it clear that he feels stronger and ready to prove he has plenty of good football ahead of him.Im not too worried about the knee, Bowman said. The knee feels great, but Im still staying on it so that anything that comes up that would hold me back wont come up.Im just excited to have another year to go out and improve on the year that I had last year, just to prove the doubters wrong and get back to the level that I was at and get the respect that I deserve.Given the three years left on Bowmans contract, this deal is a rarity, but the 49ers have been adamant about wanting to spend some of their nearly $50 million in cap space to retain some of their key pieces. Bowman obviously fits that description.In 2012, the 49ers signed Bowman to a contract extension that was set to take him through the 2018 season. He had three years and $23.55 million remaining on that deal.Although the 49ers are only three practices into this years camp, defensive coordinator Jim ONeil said he can already see a little extra bounce in Bowmans step. That Bowman serves as one of the primary leaders on a young team only makes his continued presence more valuable.I thought last year, towards the end of the year, he was kind of back to what he was pre-injury, ONeil said. But NaVorros been great. I think hes really started to step into that leadership role, and theres a lot of guys in the NFL who are lead-by-example guys. I think NaVorro has kind of taken that next step, and hes a follow-me-or-else guy, which are the kind of leaders you need to have to have a great unit in this league.With a new deal in place, the 49ers could have their leader around for seven more seasons.

Fred Warner Super Bowl Jersey . -- Arizona raced out to a big lead and did not back off, hitting the accelerator instead. Pakistan have called up 17-year-old Mohammad Asghar as a back up for legspinner Yasir Shah in the Test squad in Australia. Yasir missed the ongoing tour game in Cairns with a back problem, which prompted the PCB to send the uncapped left-arm spinner Ashgar down under.Left-arm allrounder Mohammad Nawaz is the only other spin option in Pakistans Test squad.Asghar was originally considered for the tour of Australia because he had been pulled out of the ongoing Bangladesh Premier League to play first-class cricket in Pakistan, but the selectors eventually named the same squad that played the Tests in New Zealand.He bowled only 6.2 overs and took one wicket in his first match for United Bank after returning from the BPL, but in his second game he sent down 72 overs in an innings for figures of 3 for 166. Overall, Asghar has played 17 first-class matches and taken 68 wickets at an average of 26.61 since his debut as a 15-year-old in December 2014.Yasir hurt his back during a training session at the Cazalys Stadium in Cairns on December 6. He was being treated for the issue by a doctor in Cairns, and was advised a few days rest. The first Test against Australia - a day-night match in Brisbane - begins on December 15.Yasir is visibly improving but its an important Test and we dont want to taake a risk, Amjad Hussain, Pakistan media manager, told ESPNcricinfo.ddddddddddddHe basically suffered back spasms and is being taken care of with therapy. We are hoping to have him back. But its always good to have back up to counter the worst case.Asghar was picked over experienced left-arm spinner Zulfiqar Babar, who had been Pakistans second spinner in home Tests since Abdur Rehman faded away. Babar travelled to England this summer with the squad, though he did not play a Test. A poor series in the UAE against West Indies - three wickets at 49.66 apiece - followed.The selectors said it was not that lack of form that prompted Babar to be sidelined, though.* Instead, the selectors said, with Asghar merely being cover for Yasir and they being quite confident that the legspinner will be fit to play, they wanted to bring in a young player to get a feel of the international set-up. They were not keen to call in a senior player only to be benched, especially since Babar is set to play the final of the domestic first-class Quaid-e-Azam Trophy in Karachi from December 10.*09.15GMT, December 8: This article was updated with the selectors take on Zulfiqar Babar.
