Bills quarterback Derek Anderson questionable for Bears
If Anderson cannot play, Nathan Peterman will start.
Middle linebacker Tremaine Edmunds is also questionable and not expected to play. He, too, missed practice this week because of a concussion.
Starting quarterback Josh Allen returned to practice on a limited basis Friday for the first time since injuring an elbow in Week 6 against Houston. He is out for Sunday’s game.
Defensive end Trent Murphy (knee) is out.
Buffalo (2-6) is home against Chicago (4-3).
