Why would they do that? Or was there some drama between him and the club too?
Big, big drama.
Bryan Murray told him to "go home and be a grocery clerk and play in a beer league" and at one point the Sens seemed to a actively be trying to not let him play hockey... making it impossible for him to play for ~4 months, suspended him and refused to loan him to a Swedish club.
When he left to go back to Sweden halfway through training camp to be with his brother who has Leukemia and at that point was not very well (he has stabilised since.)
Wikstrand himself said he handled it all poorly though...
“I’m really sorry about that. I should have brought it up in a more professional way and told them why I wanted to play back home. But I’m a guy who likes to keep things to myself, keep them in the family.”
But even after he said this they still basically stopped him playing for ~3 months. He released the news a few weeks after being back in Sweden in October and the Sens did not give him a loan anywhere until January. And lets be honest... the Sens have a pretty poor track record in terms of player-management relationships recently.
