This happened in Romania.
Steaua Bucharest Defender George Galamaz got attacked by a fan who ran on the pitch recently. The result of the attack is a broken zygomatic bone, which has made him deaf in his right ear. He'll have to see if its permanent or not.
The invading fan got a few kicks from the other players on the pitch, including the goalkeeper, who all ended up being sent off for violent conduct!
Later on in the match, the substitute goalkeeper got hit with a flare and had burn marks down his back.
