This is actually a disaster.
Yesterday Dynamo Moscow took on Zenit. Before the match some Zenit fans were not allowed to enter the stadium as they were drunk. During the match Zenit fans started using pyrotechnics (which is prohibited) and Anton Shunin, the goalkeeper of Dynamo was hit with it. He was down for some time while doctors tried to help him and in the meantime Zenit fans were shouting 'Shunin is a wanker'. After several minutes he was taken to the hospital and the match was cancelled.
Later Shunin wrote in the official Dynamo twitter:
"Something fell in front of me. I looked down and suddenly a firecracker exploded. I don't hear and see well now, going to the hospital for a check-up."
