FORMER Blackburn defender Martin Olsson was sent off after shockingly PUNCHING an opposition player in the face with a violent left hook.
The ex-Norwich and Swansea left-back, 35, stormed into the middle of a brawl in a cup match in Sweden.
Varbergs BoIS forward Yusuf Abdulazeez was dismissed for headbutting one of Olsson's Malmo team-mates.
The incident, which occurred in the 87th minute of a 1-1 draw, led to a host of players from both sides furiously squaring up to each other as tempers boiled over.
And this ended with a horrific moment as Olsson left one of the Varbergs players in a heap on the floor with a sickening punch.
Despite the chaotic situation proving difficult for the referee to handle, he did instantly spot the Swede's violent act and sent him packing by showing another red card.

While a fourth responded: "First I thought you're calling that little headbutt a boxing KO... but then out of nowhere, a full blown left hook!"
