Entering the uncertainty of free agency and the real possibility of playing for an NFL team not named the Denver Broncos, Elvis Dumervil wants fresh representation.

Dumervil informed his agent Marty Magid on Saturday afternoon that he wants another agent to handle his next contract. Multiple NFL sources say Dumervil is leaning toward retaining super-agent Tom Condon, who represents Broncos quarterback Peyton Manning among many high-profile players.

The three-year, $30 million terms Dumervil had left on his Broncos contract were terminated Friday when signature pages on a revised deal did not reach the team’s offices in time to meet a 2 p.m. deadline.

Wiping out Dumervil’s contract cost the Broncos nearly $4.9 million in dead money that counts against this season’s $123 payroll cap.

“The bottom line is our offer didn’t change from 11 o’clock, or 1 o’clock Eastern, to the time they decided to take the deal,” Elway said Friday. “By the time they decided, they did not give themselves enough time to send the signed documents back to beat the 2 o’clock deadline.”

Even with the switch of agents, the Broncos’ chances of re-signing Dumervil may be long as Von Miller’s pass-rush partner may want to put this contract controversy behind him by moving on.

Don’t be surprised if this saga registers up more losers than winners. Already, Magid has lost his prized client. The Broncos are confronting the real possibility of losing a three-time Pro Bowler who averaged 10½ sacks in his six playing seasons. And Dumervil may lose not only the only team he has ever played for, but perhaps millions of dollars as he enters a free-agent market that so far has been described as team-favorable.

The Baltimore Ravens were among those teams who have expressed interest in Dumervil. If the Broncos lose Dumervil, proven edge rushers who are still available in free agency include Osi Umenyiora, Dwight Freeney and John Abraham.

Meanwhile DeMaurice Smith, executive director of the NFL Players Association, has asked for an inquiry into the tardy exchange of contract documents that led the Broncos to release Dumervil.

The union has retained lawyers to look into possible remedies.

The Broncos released Dumervil on Friday because paperwork of his revised contract that included a 2013 salary cut from $12 million to $8 million was not filed to the league office by the 2 p.m. deadline. The paperwork didn’t even make it to Dove Valley until 2:06 p.m.

Until the deadline passed, Magid had seemingly done a commendable job of fighting the Broncos on their proposed pay cut. The Broncos initially asked Dumervil to take a pay cut to $6.5 million in 2013. Dumervil and Magid balked until the Broncos came up to $8 million in 2013. Additionally, the Broncos agreed to add an injury guarantee of $3.5 million to Dumervil’s 2014 salary.

Not bad agent work that went for naught when the signature page on the revised terms got hung in a fax machine between Miami, where Dumervil was positioned at Kinko’s, and the Broncos’ headquarters in Englewood.

Just like that, the snafu released Dumervil from a Broncos roster spot he held since he was part of their fourth-round dream team (Brandon Marshall and Domenik Hixon were also selected in the fourth) in the 2006 draft.

The Broncos inquired to the league office Friday if anything could be done about the fax snafu, but deadlines are deadlines. Now the union is looking into the matter while Dumervil considers putting his trust in Condon.

Besides Peyton and his brother Eli Manning, Condon and his CAA sports group represents nearly 50 percent of the league’s starting quarterbacks, eight of the last 11 MVP winners and 24 players named to the 2013 Pro Bowl.
