Jonathan Pudas equalised to make it 2-2.
For Friday's clash between Skellefteå AIK and Rögle BK, AIK's first-choice goalie Linus Söderström was back in between the posts for the home team after missoing out on the 5-2 thrashing at Rögle earlier in the week. But even he couldn't inspire AIK to improve upon a very sluggish start, and they found themselves 2-0 adrift deep in the third period.
But two quick goals drew them level and then, nearly halfway through sudden-death overtime Joakim Lindström played a lovely pass to Filip Sandberg, who scored the winner.
– It was very nice. We were incredibly strong to come back in third and then we then just keep riding that wave in the fourth. I think we deserved to win after the third period, says Sandberg afterwards.
Game six is on Sunday. Win that, and Skellefteå are through to the sem-finals.
