Anton Rödin fixed the equalizer to 2-2 in the third period and took the match to extra time.
Once there, Oula Palve scored the goal that decided both Brynäs and HV71's future.
3-2 means that Brynäs continues to play in the SHL while HV71 gets to start again in the hockey allsvenskan.
In Gävlelaget, the joy was palpable afterwards.
- I'm almost teary-eyed now.
I have felt bad every day simply explained.
Now finally, says Rödin.
Goalkeeper Samuel Ersson thought the team showed great strength during the anxious playout game.
- It's a relief. You have felt bad for so long. Somewhere we find an energy as a team and come together when it comes to the most. This is what you will bring with you throughout your career, what we did as a group when it comes to the most, he says.
