The Broncos have asked defensive end Elvis Dumervil to take a pay cut, according to an NFL source. If Dumervil doesn't agree to a reduction by March 17, when his $12 million salary for the 2013 would become automatically guaranteed, the team might release the defensive end. Dumervil's agent Marty Magid would not comment when reached by phone Wednesday. Dumervil, 29, has been one of the league's top pass rushers since he was selected by the Broncos in the fourth round of their 2006 draft. When the Broncos switched to a 3-4 defensive alignment in 2009, Dumerviil was shifted to a pass-rushing outside linebacker position where he recorded a league-most 17 sacks. The Broncos rewarded Dumervil with a six-year, $61.5 million contract extension. About two weeks after signing his new deal, though, Dumervil suffered a torn pectoral muscle in training camp that forced him to miss the entire 2010 season. Dumervil was paid $3.168 million that season, then collected $14 million in 2011 and another $14 million in 2012 when he registered 9.5 and 11 sacks, respectively. Dumervil's sack total tied for 14th in 2012 and he tied for third with six forced fumbles. Still,, a statistical and ratings company, listed Dumervil as the Broncos' most overvalued player. The statistical group also rated linebacker Von Miller, Dumervil's pass-rushing partner on the other side of the line, as the Broncos' most undervalued player. The overriding issue with value ratings is salary. It's not that the Broncos no longer believe Dumervil is a good player. They do. It's just that after paying him the superstar money of $28 million the past two seaons, the team doesn't want to write $12 million worth of checks in 2013.
