Free-agent defensive end Dwan Edwards will sign a four-year deal with the Buffalo Bills today, an NFL source confirmed.
The Ravens didn't attempt to counter the offer, the source added.
Edwards left his visit with the Bills on Tuesday without a deal. But the sides reached an agreement late Tuesday.
Edwards, the first Ravens starter to go elsewhere this season, was a 2004 second-round pick of the Ravens. He becomes the second lineman to leave the Ravens in free agency, joining Justin Bannan, who signed with the Denver Broncos.
The Buffalo visit marked Edwards' third visit during free agency.
Edwards, 28, was a late-blossoming second-round pick who started 10 games for the Ravens last season after replacing Trevor Pryce.
"It's an up-and-coming organization," Edwards told the Bills' Web site during his visit. "They play in a tough division. You got to like the challenge of that."
According to Edwards, Bannan is one of the reasons he considered Buffalo. Bannan played four years for the Bills before joining the Ravens.
"He told me a lot of great things, especially about the fans in Buffalo," Edwards said. "I thought it would be a great place for me."
The Ravens have two defensive ends on the team: Pryce and Paul Kruger.
