Tore Andre Flo scored on his Sunderland debut to deny Manchester United in a fiery 1-1 Premiership clash that was marred by the late sending off of Roy Keane.
The United captain appeared to elbow his former international team mate Jason McAteer right in front of referee Uriah Rennie, who showed Keane a straight red card in the dying seconds of the match.
Norwegian striker Flo had pounced from close range after 70 minutes to cancel out Ryan Giggs's seventh minute goal for United.
