The Denver Broncos won their season opener on Sunday night, but it came at a cost. Defensive tackle Ty Warren re-tore the tricep in his left arm in the victory over the Pittsburgh Steelers. The injury will likely cost Warren the rest of the season. Warren tore the same muscle in training camp last year and had to sit out the entire 2011 season as a result. He missed all of 2010 with a hip injury, making this potentially his third season-ending injury in as many seasons. The 31 year-old Warren signed a two-year deal with the Broncos before the 2011 season, and restructured the contract before training camp this year.
