We recently brought you the story of how a boxer brutally attacked a referee in the ring after losing a match.
Well this time it’s the so-called beautiful game that has turned ugly.
And in this incredible clip, an official finds himself on the wrong end of a nasty hook from a fuming substitute.
The incident took place during an amateur Ukrainian game in the region of Rivne, and it is still unknown as to why tempers flared the way they did.
The referee was surrounded by a baying mob of players before being knocked to the floor by a rather forceful shot to the face.
Why anyone would want to be a ref is just beyond us after this latest stunt.
