Brady leaves practice with apparent injury

FOXBOROUGH, Mass. -- There was a bit of a scare on Wednesday at New England Patriots camp, where quarterback Tom Brady went down and grabbed his left knee after an incomplete pass in 11-on-11 drills in a joint practice with the Tampa Bay Buccaneers.

A fan's video appears to show Bucs defensive lineman Adrian Clayborn push Patriots offensive lineman Nate Solder into Brady's leg just after he threw the ball. Brady immediately went down and grabbed his leg.

After practice, Clayborn told reporters he was bull-rushing Solder on the play Brady was injured, and that Solder fell back into Brady.

"You always have to stay away from the quarterback but if you have a guy on his heels, my instinct is to keep going," Clayborn said after the practice session.

After limping to the sideline under his own power, Brady missed one play before rejoining and completing the drill. Following the drill, Brady huddled with coach Bill Belichick, offensive coordinator Josh McDaniels and head trainer Jim Whalen and it was determined that Brady would not continue to practice.

He jogged off the field with Whalen under his own power.

Belichick was not available after practice, but Bucs coach Greg Schiano said he told his team not to touch the quarterback.

"Coach Belichick and I stressed to our teams: Let them throw the football,” Schiano said. “Rush the passer, but go by them and don't get around them. I can't tell you [more] because I didn't see what happened."

The severity of the injury is unclear, but whatever Brady felt on play was enough that the team wanted to be cautious.

Brady missed the 2008 season after tearing the ACL on that same left knee in the first quarter of play in Week 1 against the Kansas City Chiefs.
