It was Tom Nilsson who took the lead with a shot that unfortunately hit teammate Linus Nässén's face.
The Frölunda player sat down directly on the ice and then had to be led off the ice.
According to C More, he had to be stitched up.
Before the incident, Färjestad had taken the lead through a neat goal by Joakim Nygård.
But Frölunda managed to turn around.
First through Patrik Carlsson in numerical superiority and then a class goal by Max Friberg.
With a few minutes left to play, Joel Lundqvist scored 3-1 from close range.
After that, Färjestad managed to reduce through Remi Elie, before Loui Eriksson made it 4-2 in an empty net.
Joakim Nygård also set 4-3.
After the match, it got really annoying between the teams after a situation where team captains Joel Lundqvist and Linus Johansson were involved.
- These are special matches against Färjestad.
Always special to come here and often good matches.
It's fun to be here.
It was back and forth towards the end.
We work well, even if we don't make a clear match, says Lundqvist to C More.
Frölunda is third in the SHL table with Färjestad just behind.
