Denver Broncos defensive end Jason Hunter is out at least two months with a torn triceps and might miss the entire season. Hunter is the team's third defensive lineman to suffer a serious injury at training camp in the last two years. Elvis Dumervil missed the 2010 season with a torn chest muscle and Ty Warren missed last season with a torn triceps. Hunter had supplanted Robert Ayers as the starter at left end two weeks ago. He could be replaced by rookie Derek Wolfe, the team's top draft choice who had two sacks at Chicago last week, or Ayers.
