The Pittsburgh Steelers, who finished the 1988 season with their poorest record in nearly two decades, Tuesday announced the resignation of defensive coordinator Tony Dungy and the firing of four assistant coaches. Dismissal of some assistants had been expected, but Dungy's resignation came as a surprise.

The assistants let go were linebackers coach Jed Hughes, guards-centers coach Hal Hunter, special teams coach Dennis Fitzgerald and conditioning coach Walt Evans.
