The Buffalo Bills granted the Cleveland Browns permission to interview defensive line coach Anthony Weaver.
Weaver, 33, is a former Ravens and Texans defensive end.
He worked for Browns coach Mike Pettine for the Bills and New York Jets.
Pettine has already hired three former Buffalo assistants: Jim O'Neil as defensive coordinator, Brian Fluery as assistant linebackers coach and Jeff Hafley as secondary coach.
