Englewood, CO - Denver Broncos linebacker Danny Trevathan was placed back on the active roster in time for Sunday's pivotal AFC West clash at San Diego.

Trevathan, Denver's leading tackler during the team's AFC championship 2013 season, has been sidelined since mid-October due to a fractured left kneecap. The third-year pro has played in just two games this season before being placed on injured reserve/designated to return following the Broncos' Week 6 matchup against the New York Jets.

While Trevathan is set to return, running back Montee Ball will officially miss the remainder of the season after being placed on injured reserve on Saturday. Safety Quinton Carter was also moved to IR.

Ball has been limited to just five games by a groin problem. The 2013 second- round pick sat out five straight weeks before briefly returning for Denver's Nov. 16 game at St. Louis, when he aggravated the injury.

The Broncos' No. 1 back to begin the season, Ball had 172 rushing yards and one touchdown on 55 carries before getting hurt.

Carter, who is dealing with a lingering knee injury, recorded 21 tackles and one sack in 11 games this season.

Denver also promoted tight end Dominique Jones from the practice squad during Saturday's moves.
