As reported by multiple sources out of New England Patriots camp, quarterback Tom Brady left practice today with an apparent injury to his left knee. During a joint-practice with the Tampa Bay Buccaneers, Brady suddenly felt a pain in his left knee. According to ESPN’s Mike Reiss, there did not appear to be any contact during the play when Brady was injured:

Brady returned to practice after taking one play off, but did not last long before walking off the field to see the Patriots training staff. The New England franchise quarterback talked it over with coach Bill Belichick before leaving the field.

The left leg is the same side on which Brady tore his ACL in the very first game of the 2008 season, causing him to miss the remainder of the year. Brady’s participation in preseason this year was already heightened due to the prevalence of new receivers, and the veteran quarterback was making an attempt to develop chemistry with his new targets.

The Patriots have third-year backup Ryan Mallett, though the former Arkansas standout has never seen significant playing time in the NFL. In his entire career, he has only completed one pass in a regular season game.

Behind Mallett, there is current third-stringer, Tim Tebow. The college star started for the Denver Broncos for most of the 2011 season, helping to lead the team to a miraculous division title, and a subsequent victory against he Pittsburgh Steelers in the first round of the playoffs before eventually losing to Brady and the Patriots in the Divisional round.
