Running back DeAngelo Williams has also been ruled out with a foot injury. Williams replaced Le'Veon Bell early in the season and rushed for more than 900 yards and 11 touchdowns, giving the Steelers a dependable backfield option.
He missed last week's Wildcard game in Cincinnati and he hasn't improved enough yet to be cleared for practice, let alone contact in a live game.
For what it's worth, Big Ben practiced in full Friday and although he's officially listed as questionable for Sunday, all signs point to him starting the game.
If Big Ben's on the field, anything is possible and you can believe the Broncos will game-plan accordingly.
