It was during the beginning of the match that the accident occurred.
Leksand's Max Véronneau - who leads and will win the shooting league in the regular season - went into Brynås goalkeeper and went into the ice.
He lay in pain, was treated on the ice and finally got up.
The forward - who was sent off for driving into the cage keeper Veini Vehvilainen - was then helped into the locker room.
It is unclear how serious the injury is.
C More reports that the Canadian has been taken to hospital to examine his arm.
The match is in progress. Brynäs leads 4-0.
