Dahlén was hit by Tommi Tikka in a corner in the first period and left the ice in pain.
In the period break, coach Ante Karlsson announced that it was playoffs for the 26-year-old.
Despite the break, Timrå managed to win the away match and in the final stages of the match the club also came with reassuring information about their star.
“As most people saw, Jonathan Dahlén left tonight’s match early. We now have positive news and can announce that he is doing well,” the club wrote on X.
