The Patriots have lost Pro Bowl WR Wes Welker for the rest of the season due to a torn ACL and MCL in his left knee that he injured against the Texans yesterday.  Welker played in 14 games this season for the Patriots and he caught 123 passes for 1,348 yards (11.0 avg) with 4 TD grabs.  He also carried the ball 5 times for 36 yards (7.2 ypc) this year.  Rookie Julian Edelman will likely have to step up for the Patriots in Welker’s role of the tough guy over the middle.  Edelman has played in 11 games this season for the Patriots and he has caught 37 passes for 359 yards (9.7 avg) with a TD grab.  He has also carried the ball 2 times for 5 yards (2.5 ypc) this season.  This is a huge blow to the Patriots’ offense as Welker is Tom Brady’s security blanket in the passing game.
