FOXBOROUGH, Mass. — Tom Brady looks just fine. His fans and teammates are relieved.

The key to the success of the New England Patriots participated fully in the team’s walkthrough Thursday. He jogged with other players at the start. He dropped back normally to throw passes. And he didn’t limp.

An alarming situation — he had left Wednesday’s practice with an apparent left knee injury — was just a false alarm.

“I’m good,” was all Brady told waiting media members as he walked off the practice field Thursday after removing the black brace he wore during the workout. “You can all go home.”

Then, after signing some autographs and posing for pictures, the star quarterback walked back into Gillette Stadium where he may or may not play in Friday night’s exhibition game against the Tampa Bay Buccaneers.

Patriots coach Bill Belichick didn’t speak with reporters after the third and final day of joint practices with the Buccaneers.

Brady was knocked down by left tackle Nate Solder after releasing a pass midway through Wednesday’s session. Solder had been pushed into Brady by Buccaneers defensive end Adrian Clayborn. A person with knowledge of the situation said Brady sprained his left knee nd an MRI was negative.
