The Steelers struggled early as Neil O'Donnell took over from Bubby Brister at quarterback. The Steelers ended the season winning their last two games, 17–10, over the Cincinnati Bengals and Cleveland Browns at Three Rivers Stadium to finish with a 7–9 record. Following the season Chuck Noll announced his retirement, ending his 23-year career in which he won four Super Bowls while posting an overall record of 209–156–1.
