Elvis Dumervil is putting his seven seasons in Denver and one bizarre fax fiasco behind him after agreeing to a five-year deal with the Baltimore Ravens on Sunday.

Dumervil tweeted his thanks to the Broncos and team owner Pat Bowlen shortly after rejecting the club's latest contract proposal.

"Can't say enough about the Broncos fans, my great teammates, equipment staff, training staff, media staff, Mr. Bowlen, Coach Fox, John Elway and the city of Denver. Its been an unforgettable 7 years. I am looking fwd to this next chapter of my career," Dumervil wrote.

So the Broncos now find themselves in need of a new pass-rushing partner for Von Miller.

Elway, the Broncos' football operations chief, issued a statement Sunday saying the Broncos "worked diligently over the last week" to re-sign Dumervil, a defensive captain, but "are now moving forward without him."

Free agents John Abraham 34, and Dwight Freeney, 33, visited the Broncos last week, and it's expected one of them will sign on soon to replace Dumervil, 29.

On March 15, Dumervil waffled but finally agreed to reduce his 2013 salary from $12 million to $8 million in Denver as part of a renegotiated three-year, $30 million contract. But the paperwork didn't reach the NFL offices in time, and the Broncos were forced to release him to avoid having to pay him the full $12 million for next season.

Dumervil fired agent Marty Magid after that deadline debacle and hired agent Tom Condon.

Bears: Former Carolina Panthers linebacker James Anderson agreed to a one-year contract with Chicago, the latest move in a major overhaul at the position.

The deal comes two days after the Bears signed D.J. Williams from Denver to replace Brian Urlacher.

Anderson was released earlier this month. He figures to take over at strong side for Nick Roach, who signed with the Raiders. The only returning starting linebacker for Chicago is Lance Briggs on the weak side.

Falcons: Several reports indicated free agent defensive end Osi Umenyiora was close to an agreement with Atlanta and could officially join the Falcons as early as Monday.

Quoting an anonymous source, Pro Football Talk was the first to report late Saturday night that the longtime New York Giants standout would soon be signing with the Falcons to replace the recently released Abraham.
