(Reuters) - New England Patriots quarterback Tom Brady missed a second straight practice on Thursday due to a knee injury, the BostonHerald reported, putting his availability for Sunday's game in doubt. The origin of Brady's injury is unclear as he played the full game in Patriots' 30-17 win against the San Francisco 49ers on Sunday. The Patriots are set to play New York Jets on Sunday and the 39-year-old Brady would likely need to practice on Friday before playing in that contest.
