The Bills placed Smoot (wrist) on injured reserve Tuesday.
Smoot injured his wrist during the Bills' Week 9 win over the Dolphins. He'll be forced to miss at least the next four regular-season games, and the earliest he can return is Week 15 against the Lions on Sunday, Dec. 15. Across seven regular-season outings, Smoot tallied 12 tackles (eight solo), including 1.5 sacks, and one forced fumble.
