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.

TUSCALOOSA, Ala. -- Even Nick Saban sometimes has to deliver an I told you so to his team, along with a few other choice words.No. 1 Alabamas slow-starting 31-3 victory over FCS team Chattanooga on Saturday night was one of those times.Jalen Hurts passed for three touchdowns and rushed for 68 yards, but the Crimson Tide (11-0) spotted the Mocs (8-3) the games first three points and didnt really shake them until late in the third quarter. The defense had a more Bama-like performance, and hasnt given up a touchdown in 13 quarters.Sabans halftime message after a week of trying to get his players to take Chattanooga seriously: I said, `Do you believe me now?Id been telling them all week, Saban said. The rest wed better bleep out.Hurts was 15 of 21 for 136 yards a week after torching Mississippi State for 347 yards. He had a 47-yard TD pass to Calvin Ridley and added two 1-yarders to Gehrig Dieter, including one in the final minutes that made the score look a little closer to what most expected. Hurts set Alabamas single-season record for rushing yards by a quarterback.Damien Harris rushed for 91 yards and a touchdown and Ridley gained 94 yards on seven catches.Alabama wide receiver ArDarius Stewart did not play in the game, and Saban indicated he was held out because sometimes we have players that have a violation of our standard of behavior.It was a milestone win for Saban, whose 41-5 record as the No. 1 team gives him the most of any coach. He had been tied with Ohio States Woody Hayes (40-4-1) and Florida States Bobby Bowden (40-5).This one came after a string of more impressive performances against Southeastern Conference opponents.I worried about it all week long, Saban said. When youre playing conference games every week and youre playing big games every week, its really hard to get guys not to have a letdown.Chattanoogas first-quarter field goal put Alabama behind for the first time since Kentuckky scored the first three points on Oct.dddddddddddd 1. The Mocs trailed just 14-3 until deep into the third quarter before Harris raced 25 yards for a touchdown.Alejandro Bennifield completed 16 of 21 passes for 106 yards for the Mocs, who sacked Hurts three times.I remember playing them here in 2013 and barely recording a first down, Chattanooga coach Russ Huesman said. They have got a really good football team, and they probably slept walked coming into this game. I am not trying to think that they were all jacked up to play Chattanooga, but our guys were pretty excited to play, and I am awful proud of them.Alabama wasnt exactly pushing the Mocs around early. Chattanooga stopped two runs from the 1-yard line in the second quarter before Hurts rolled right on fourth down and hit Dieter in the end zone for a 14-3 lead.That was set up by a muffed punt at the 9.I guess we just underestimated them, Ridley said.THE TAKEAWAYChattanooga: Was almost even in total yards with Alabama midway through the third quarter. Didnt allow a sack to a defense that came in with the most in the nation.Alabama: It was probably the least impressive performance of the season, considering what `Bama is expected to do to FCS teams. Left tackle Cam Robinson and backup Korren Kirven, who started at right guard, both left late with shoulder injuries. Saban expects them to be able to play in the Iron Bowl.POLL IMPLICATIONSChattanooga: Came in ranked No. 11 in the FCS coaches poll and shouldnt be judged much for this one.Alabama: Still a lock to be No. 1 in the AP poll and playoff rankings, especially with teams behind Tide struggling.UP NEXTChattanooga: Finished the regular season and awaits its playoff fate.Alabama: Hosts Auburn in the Iron Bowl seeking a third straight win over its in-state rival.
