The Buffalo Bills have reached an extension with guard Kraig Urbik on a contract extension, says ESPN.com.

The deal is for four years and worth $15 million, according to the report.

Urbik is a two-year starter in Buffalo and apparently will be part of the team's plans despite the uncertainty that swirls around both head coach Chan Gailey and general manager Buddy Nix as the team has struggled to a 5-9 record.
