The Black Cats head to Carrow Road in a potentially huge encounter in the relegation battle on Saturday, April 16, with the game now kicking off at 12.45pm.
Sunderland’s Stadium of Light encounters against title-chasing pair Arsenal and Leicester have also been rearranged, with both games moved to the Sunday.
The clash with Leicester will now take place on Sunday, April 10 (kick-off 1.30pm), while the Arsenal encounter is on Sunday, April 24 (kick-off 2.05pm).
However, the Arsenal game could be rescheduled again with the FA Cup semi-finals that weekend and the Gunners still in the competition.
