Frazier Campbell scored on his Sunderland debut as two late goals lifted the Black Cats to a 2-0 win at Peterborough.

After a frustrating night in front of goal, Sunderland eventually found a way through as the game moved into the final 10 minutes when David Healy's cross was turned in by the unfortunate Daniel Blanchett for an own goal.

Three minutes later, Campbell was flattened by Sam Gaughran, and then stepped up to score the penalty.
