SUNDERLAND and Oxford players were caught off guard as sprinklers turned on mid-match.
The incident happened quickly after kick-off with sprinklers going off all over the pitch in the first minute.
Oxford were not too pleased as they were on the attack at the time, with the referee calling a halt to play.
Players were seen with their arms up in the air - Oxford striker Mark Harris was seen gesturing towards the dugout area.
Their frustrations were made worse 15 minutes later as Jobe Bellingham headed in the opener for the hosts.
The Black Cats then doubled their lead after half-time through Wilson Isidor.
