Buffalo Bills head coach Sean McDermott has officially ruled out slot cornerback Taron Johnson (forearm) and linebacker Terrel Bernard (pec) for Sunday night’s game in Baltimore.

Bernard participated only in Thursday’s practice, during which he wore a red non-contact jersey in individual drills during the viewing session available to the media. McDermott said that Bernard is expected to continue participating in drills on Friday.

Cornerback Kaiir Elam (neck) was limited Thursday, but McDermott expects him to be ready for Week 4.

Additionally, rookie offensive lineman Tylan Grable was placed on injured reserve (groin) earlier this week, and the team signed offensive lineman Will Clapp on their 53-man roster.
