Entering the uncertainty of free agency and the real possibility of playing for an NFL team not named the 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 league sources said 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 didn’t reach team headquarters 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,” Broncos executive John 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 not be good, because 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 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. Also, Dumervil may lose not just the only NFL team he has 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 are among the teams that have expressed interest in Dumervil. If the Broncos lose Dumervil, proven edge pass rushers still available in free agency include Osi Umenyiora, Dwight Freeney and John Abraham.

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 wasn’t filed to NFL headquarters by the 2 p.m. deadline. The paperwork didn’t even make it to Broncos headquarters until 2:06 p.m.

Until the deadline passed, Magid seemingly had 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 for 2013. The Broncos agreed to add an injury guarantee of $3.5 million to Dumervil’s 2014 salary.

That’s not bad agent work, but it all went for naught when the signature page on the revised contract terms got held up in a fax machine between Miami, where Dumervil was positioned at Kinko’s, and Broncos headquarters.

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

The Broncos asked the NFL on Friday if anything could be done about the fax fiasco, but deadlines are deadlines. Now the NFLPA is looking into the matter while Dumervil considers putting his trust in Condon.

Besides Peyton and his brother Eli Manning of the New York Giants, Condon and his CAA sports group represent 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.
