Broncos Lose Starting Center Dan Koppen for Season
(ENGLEWOOD, Colo.) -- Denver Broncos starting center Dan Koppen tore his ACL in 9-on-7 drills Sunday and will miss the entire 2013 NFL season. "I always cringe," John Fox said after practice. "You never like to see players get injured, particularly severely injured. But you understand when you do this long enough, whether you're a player or a coach, that this happens."
