Just how long will Elvis Dumervil be out?

Denver Broncos coach Josh McDaniels said the team has no timetable for the recovery of Elvis Dumervil. He suffered a torn pectoral muscle in practice Wednesday night.

ESPN’s Adam Schefter is reporting that Dumervil will be out four months. Thus, there is a chance Denver could still use him this season.

Still, McDaniels acknowledged there is a chance Dumervil could need surgery. I was in contact with ESPN medical analyst Stephania Bell. She indicated surgery would very likely mean Dumervil would be out for the season. Bell indicated that is a tough injury to come back from quickly.

“Given the incredible demands on the muscle for anyone playing a defensive position who has to tackle with an outstretched arm, it makes it even more important that he is fully healed and at absolute full strength before returning, or else he will easily re-injure it. … which means, you guessed it, less likelihood in my eyes that he’s able to return,” Bell wrote in an email Thursday.

Football Outsidersl looked at the history of the injury and concluded that there is little chance Dumervil will come back this season.

Denver did shelve two players for the season Thursday night. It put receiver Kenny McKinley and safety Josh Barrett on the injured reserve. Both players were key special teams players and McKinley had a chance to be in the receiving rotation. Denver signed receiver Patrick Carter and Britt Davis. Both have an uphill battle to make the 53-man roster.
