Sunderland saw their four-game unbeaten run in the Championship brought to an end by Swansea City at the Stadium of Light. Luke O'Nien was shown a straight red card in the first half for a poor challenge on Oli Cooper, which left the Black Cats to play for more than 70 minutes shorthanded.
Joel Piroe put the Swans in front just after half-time, before Dan Neil levelled things up midway through the second period. But Liam Cullen restored the visitors' lead just minutes later, and then Cooper gave Swansea breathing space when he gave them a two-goal cushion 12 minutes from time.
Sunderland slipped to tenth in the table, three points outside the play-off spots. Swansea climbed to 11th, and are now level on points with the Wearsiders.
