FOXBOROUGH, Mass. -- Tom Brady walked off the field under his own power. Several teammates didnt think he was hurt badly when he grabbed his left knee after being knocked down. Yet the possibility that the New England Patriots might lose their star quarterback caused a scare at the teams joint practice with the Tampa Bay Buccaneers on Wednesday. A person with knowledge of the injury said an MRI was negative and Brady was day-to-day with a left knee sprain. Asked if Brady might play Friday night in an exhibition game against the Buccaneers, the person said he didnt know. The person spoke on condition of anonymity because the Patriots didnt make an announcement. The two-time league MVP had a season-ending injury to the same knee in the 2008 opener. Brady was injured midway through practice Wednesday when left tackle Nate Solder was pushed into him by Tampa Bay defensive end Adrian Clayborn. Brady, entering his 14th NFL season, fell, rocked backward on the ground and held his left knee. He went to the sideline then returned for a few more plays before talking with coach Bill Belichick and leaving the field toward the teams indoor practice facility next to it. "Youve always got to stay away from the quarterback (in practice)," Clayborn said. "You got a guy on his heels and my instinct is to keep going, so thats what I did." The contact came just as Brady threw a long incompletion down the right sideline toward rookie Aaron Dobson. "Were always working to protect," Solder said. "Ill have to see what happened on the film. I screwed some things up here and there." In 2008, Brady tore the anterior cruciate ligament in his left knee. The Patriots missed the playoffs that season. He has played every game since then and the team reached the playoffs in all four seasons. New England is favoured to win the weak AFC East for the 10th time in 11 years. Losing Brady would have made that much tougher. After Brady left the field, third-year pro Ryan Mallett played with the first offensive unit and Tim Tebow, on his 26th birthday, played with the second team. Mallett threw an interception soon after taking over. "Im just trying to do my job," Mallett said. "Im sure Tom will be fine and well just go on." In his first series after Brady left, Tebow completed three of seven passes and looked fairly sharp. One of his passes was dropped. Tebow left practice without speaking with reporters. "Anytime anybody, especially a teammate, goes down its a dark cloud. Its unfortunate," Patriots running back Shane Vereen said. "He went back out there, but well see." Running back LaGarrette Blount was optimistic. "He walked off," Blount said. "Im sure hes cool. Im sure hes fine." But shortly before Blount spoke, a black helicopter landed on a field adjacent to the one where Brady was injured. Cameramen, apparently concerned that Brady might be airlifted to a hospital, rushed to record the landing. "The helicopter has nothing to do with Tom," Patriots owner Jonathan Kraft said on WBZ-FM. Tampa Bay coach Greg Schiano said he and Belichick stress to their players to rush the passer but let him throw the football and go past him. "I didnt get to see" the hit on Brady, Schiano said. "I saw him laying there afterward. ... I hope hes OK." Losing Brady would leave the Patriots without a proven starting quarterback. Mallett has thrown just four passes in his first two seasons and has been inconsistent during training camp. Tebow signed as a free agent on June 10 and has struggled with his throwing mechanics, a problem hes had since being drafted by the Denver Broncos in the first round in 2010. "The big thing is just his familiarity with the offence, the way we do things -- the play calling, the reads, formationing, just general things we do," Belichick said of Tebow. "The quarterback has to have a good understanding of all that. The more you do it, the more you get comfortable with it and the better you can execute it. I think thats no different, really, than any other young quarterback or quarterback coming into a new system." In the Patriots 31-22 exhibition win over the Philadelphia Eagles on Friday night, Mallett completed 9 of 18 passes for 97 yards. Tebow went 4 for 12 for 55 yards with three sacks and ran four times for 31 yards. Brady completed 7 of 8 passes for 65 yards and one touchdown and left after the first two series.

Marcos Maidana did everything Saturday night but beat Mayweather, taking him 12 tough rounds before losing a majority decision. Mayweather remained unbeaten, but not by much. Maidana swarmed all over him from the opening bell and gave him perhaps his toughest fight in a 16-year professional career. Cut over his eye and temporarily blinded by a head butt in the fourth round, Mayweather had to rally in the last half of the fight to avoid losing for the first time since he was beaten on a controversial decision in the 1996 Olympics. In the end, though, Mayweather got the win — just as he did in his previous 45 fights in a decision that was met with disbelief by Maidana and booed heavily by the crowd. He retained his welterweight title by winning 117-111 on one scorecard and 116-112 on another. A third judge had it even at 114-114. The Associated Press scored it for Mayweather 115-113. Maidana threw far more punches, but Mayweather was more accurate with his as the two battled into the late rounds with the fight still very much in doubt. Cheered on by a large contingent of Argentine fans, Maidana took the fight to Mayweather, who was cut by the right eye in the fourth round by an accidental head butt. "It was a tough, competitive fight," Mayweather said. "I normally like to go out there and box and move. But he put pressure on me. I wanted to give the fans what they wanted to see so I stood and fought him. Maidana raised his arms in victory when the final bell sounded, and Mayweather watched pensively from his corner as the scorecards were added up before he was declared the winner. "I think I won the fight," Maidana said. "He didnt fight like a man." Punch stats by Compubox showed Mayweather landing 230 of 426 punches to 221 of 858 for Maidana. It was the most punches landed by any fighter against Mayweather in 38 fights where punch stats were compiled. Maidana had a big lead in the early rounds through his constant aggression.dddddddddddd. But Mayweather won five of the last seven rounds on two scorecards and six of seven on a third to pull out the win by a narrow margin. "I couldnt see for two rounds after the head butt," Mayweather said. "After I could see again it didnt both me. Thats what champions do, they survive and adjust." Maidana had said before the fight he was going to treat Mayweather like any other fighter and go right after him. He did just that, bringing the sellout crowd at the MGM Grand hotel to its feet as he landed some big overhand right hands to the top of Mayweathers head. "He never hurt me with a punch," Maidana said. "He wasnt that tough, I thought I won." Maidana complained about being forced to fight with gloves he didnt want to use when the two camps engaged in a standoff over gloves at the rules meeting a day earlier. "If I would have had my gloves I would have knocked him out," Maidana said. "They took away my advantage." Mayweather, who earned $32 million for the fight, was a 6-1 favourite coming to remain unbeaten. He had picked Maidana as an opponent because Maidana beat Adrien Broner in an upset in December, but he almost made the wrong pick. Mayweather seemed confused early and unable to adapt to the wild punches thrown by Maidana. It wasnt until the middle rounds that he got into more of a rhythm, hitting Maidana with hooks to the body and right punches to the head. Still, the fight was in doubt late as Maidana wouldnt quit coming forward. With the crowd on its feet in the final round he tried to land big punches, but Mayweather was able to escape most of them. Maidana, who was cheered by the crowd as he left the ring, said he wanted a rematch, and both promoter Richard Schaefer and Mayweather said he just might get one after nearly pulling off one of the biggest upsets in recent years. "If the fans want to see it again, lets do it again," Mayweather said. ' ' '
