Sunderland's four-game unbeaten run came to an end as the Black Cats were beaten by Swansea City in South Wales. The Black Cats trailed 2-0 at the break after a woeful first half performance, with Ollie Cooper's deflected shot early in the half and a close-range Harry Darling finish in injury-time doing the damage.
But Tony Mowbray's side gave themselves a chance when Jack Clarke scored just five minutes into the second period. The Wearsiders were much-improved in the second 45 but they could not find a second goal, while at the other end Anthony Patterson made a fine save from Joel Piroe to prevent Swansea putting the game out of reach.
Defeat saw Sunderland slip three places to 11th in the Championship table. Mowbray made one change to the side that started the midweek draw against Blackpool on Wearside, with Dan Neil restored to the side in place of Amad Diallo.
