It was during Sunday's SHL match against Skellefteå that Rödin flew into the rim and lay down.
The star came back and played the match with a tightly wrapped wrist, but after a medical examination it has been established that it is broken.
"He was x-rayed after the match yesterday and a fracture of a forearm was determined.
He is now plastered.
We will talk to specialists to see if we should operate or not.
Before we get an answer from there, it is difficult to determine a time frame for when he can be recovered ", Brynäs writes on his website.
In addition, Greg Scott, who went on an ugly tackle by Skellefteå's Darren Nowick, has a feared concussion.
"We investigated him after the situation during the match yesterday and suspect a concussion."
