An MRI on the left knee on New England Patriots quarterback Tom Brady came back negative after going down in a joint practice with the Tampa Bay Buccaneers on Wednesday.

ESPN NFL Insider Adam Schefter reported that the Patriots plan to re-examine Brady on Thursday, but it is believed that the quarterback will likely participate in practice.

Video taken by a fan showed Bucs defensive lineman Adrian Clayborn push Patriots offensive lineman Nate Solder into Brady's leg just after Brady threw the ball. Brady immediately went down and grabbed his leg.

Clayborn told reporters he was bull-rushing Solder on the play on which 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.

Solder said he wasn't sure exactly what happened on the play.

"Anytime someone goes down, we worry about it," Solder said. "So we'll see what happened. I don't know at this point. ... There were a few different things that happened, so I'll have to see it [on film]."

Patriots president Jonathan Kraft wasn't at the practice when the injury occurred, but in an interview with Boston sports radio station 98.5 The Sports Hub, Kraft said he made a phone call to check on Brady's status and was told that it "hopefully did not appear to be that bad."

"I understand from people who were standing out here it may have looked serious," Kraft said. "I don't have a definitive answer. And in classic [coach] Bill Belichick fashion, I will tell you a little bit more though, and just say I don't believe it's serious, but I do not know."
