NFL Network’s Tom Pelissero reports Bengals EDGE Shemar Stewart (knee) will be placed on injured reserve.

Stewart missed multiple games with an ankle injury and is now set to miss at least the next four games due to a knee injury. The 22-year-old defensive end will miss most of his rookie season due to injury and his play wasn’t anything to write home about when he was actually on the field. His 36.9 overall PFF grade was dead last among 114 defensive ends.
