Jamie Vardy's first-half header gave Championship leaders Leicester City a crucial win against Sunderland to keep their title bid on track.
The Foxes went into the game on a run of three straight league defeats, which had seen their lead at the top of the table cut from 12 to just three points.
But Vardy's 10th goal of the season, a headed finish after a Kiernan Dewsbury-Hall free kick from the left, saw them home in an uninspiring encounter at the Stadium of Light.
The Black Cats lost their fifth game in a row, falling from the play-off spots to 10th place in that time, 10 points outside the top six.
