Tempers flared towards the end of Sunday's game at the Riverside.
With the score 2-1 to Manchester United at that point, relegation threatened Middlesbrough sensed an equaliser.
As they prepared to send a late free-kick into the United box, Rudy Gestede was seen tangling with Eric Bailly on the edge of the penalty area. Initially not picked up by the live footage of the game, replays later showed how the pair had to be pulled apart by their respective teammates.
