A couple weeks ago, we were told by Swedish news outlet Expressen that Joakim Andersson was preparing to sign a contract to play in the SHL next season. Today, we have as strong a confirmation as you're going to get:
That's a screenshot from this video posted on Örebro's official team website where Andersson announces that he's joining the team. I'd say that's a real super-duper strong hint he's gone, but just in case you want to read another Expressen article on it, they have it as well.
