An MRI exam for a suspected elbow injury revealed defensive tackle Ty Warren of the Broncos suffered a season-ending injury for the third straight season.
Warren was the only player injured for the Broncos in Sunday night's win against the Steelers. He was seeing his first action in two full seasons after hip and triceps injuries in the previous two seasons.
Coach John Fox announced Monday afternoon that Warren had a torn biceps and said Warren would likely miss the remainder of the season.
The Broncos are short on run stoppers in the middle of their defense and might have to look for free agent help or consider acquiring a veteran via trade.
Warren underwent surgery in August 2011 after suffering a partial tear of the triceps in his first training camp with the Broncos after the former first-round pick was released by the Patriots. He was placed on injured reserve in mid-September 2011.
Warren, 31, started 103 games and won three Super Bowl rings with the Patriots. He played collegiately at Texas A&M.
