Derek Anderson (concussion) out for Buffalo in Week 9

Buffalo Bills quarterback Derek Anderson will not play on Sunday in the team's Week 9 game against the Chicago Bears.

What It Means:

Anderson was concussed on Monday night against the New England Patriots, and it appears that he hasn't recovered enough to play. Nathan Peterman will start in his stead.

So far this season, Anderson has gone 42/70 for 465 yards and four touchdowns in two games.
