Broncos will place DT Kevin Vickerson (hip) on injured reserve, ending his season. The Broncos can't afford to wait on Vickerson in the hopes his dislocated hip will heal in time for the playoffs. Instead, they'll use Sylvester Williams and Mitch Unrein next to Terrance Knighton and sign a body for defensive tackle depth. Vickerson will head to free agency with 22 tackles and one sack in 11 games. He graded out as ProFootballFocus' No. 61 nose/defensive tackle among 70 qualifiers.
