The Arizona Cardinals have fired defensive coordinator Clancy Pendergast and may be looking to the Steelers to replace him.
Arizona has contacted the Steelers for permission to speak to linebackers coach Keith Butler about the opening.
Given that it would be a promotion, the Steelers shouldn't be able to say no. But I've been unable to confirm that one way or another.
Butler was seen as the eventual replacement for defensive coordinator Dick LeBeau in Pittsburgh when LeBeau finally decides to walk into the sunset.
Butler was on staff with Ken Whisenhunt and Russ Grimm when they were in Pittsburgh.
