Denver Broncos backup offensive lineman Frank Crum (illness) has been ruled out for Sunday’s playoff game against the Buffalo Bills after missing two straight weeks of practice.

Both players will challenge Denver’s inside linebackers, who have been inconsistent in coverage. Broncos inside linebacker Justin Strnad gave up 39 catches for 450 yards and a passer rating of 104.2, while Cody Barton allowed 34 catches for 395 yards, a touchdown and passer rating of 95.3 while recording two interceptions.
