He said paramedics attended to the man and he was taken to hospital. He has since been upgraded to stable.

Xxavier Barra, who witnessed the altercation unfold, said his team Galatasaray United was playing Winnipeg Croatia on Thursday when, in the final five minutes of play, a player on the Croatia team was given a yellow card.

He said the player then went on to taunt the ref and asked to be given another yellow card.

When the ref went to do that the player punched him and he fell to the ground unconscious, Barra said.

Barra alleged that the player then kicked the ref twice.

The man is facing a charge of assault causing bodily harm. He's been released on a promise to appear.

He is not allowed to play in another match until a hearing is held.

In a statement released Monday, the Manitoba Soccer Association (MSA) says its discipline committee will hold a hearing "as soon as possible" into the alleged attack.

"The MSA does want to ensure due process is followed for all parties involved but we are clear that we don’t tolerate violence on the playing field," association executive director Héctor Vergara said in the statement.

The Manitoba Major Soccer League says it expects the MSA to hold a hearing soon and "appropriate disciplinary action will be taken against the accused party."
