Along with Brian Leonard sitting out on Wednesday, Bengals linebacker and defensive end Dontay Moch was also out during Wednesday's practice with an unknown ailment. Moch also missed Thursday's practice against the Cleveland Browns, but returned with full participation on Friday and played a handful of defensive snaps.
When asked what the problem was, and if it was related to his migraine headaches that he's suffered in the past, head coach Marvin Lewis simply called it "an illness."
