Tom Brady has left the New England Patriots practice on Wednesday with a knee injury.

NFL.com, which broke the story in the afternoon, said reporters watched Brady clutch his left knee, limp off, and then returned to the field.

The Patriots were practicing against the Tampa Bay Buccaneers.

He had to be checked out by trainers.

Brady tore his ACL in 2008, and was out for that season.
