Frölunda lacked seven players due to injury and illness for the top meeting with Brynäs.
In addition, the list grew.
Forward Linus Weissbach received a hard tackle from Miks Indrasis in Brynäs and was forced to leave.
Jakob Silfverberg gave Brynäs the lead after just over seven minutes and barely seven minutes into the third period, Linus Ölund increased the score to 2–0.
The win means that Brynäs takes an increasingly firm grip on the series win.
The team's lead over new number two Luleå is a whole eleven points with five rounds left to play.
I'm extremely happy about this win, I think we play a really good hockey match in three periods, says coach Niklas Gällstedt whose team came from a worse period with only one win in four matches.
Frölunda dropped two positions due to the loss and is now fourth.
