Bills' Justin Zimmer: Out for season

Zimmer (knee) was placed on injured reserve Thursday and will miss the remainder of the season.

Zimmer's knee injury will require season-ending surgery. This injury will hurt Buffalo's defensive line depth as the backup defensive tackle normally accounted for around 40 percent of defensive snaps. Star Lotulelei and Harrison Phillips and perhaps Vernon Butler will have to step into a bigger role in Zimmer's absence.
