Tyson Fury appeared to hit Francis Ngannou with his elbow during his controversial win on Saturday night.
The WBC heavyweight world champion controversially beat the former UFC star by split decision in Riyadh after being knocked down in the third round.
The judges scored the fight 94-95, 96-93 and 95-94 in favour of Fury, a result which was widely panned within the boxing world and beyond.
Making his professional boxing debut, Ngannou surprised the Gypsy King and even wore an illegal shot in the sixth round after Fury threw an elbow that landed clean on his face.
