Not sure how much truth something like this holds, but I thought it was interesting... to say the least. Someone posted this in the comments section of an MLive article; they refused to give a link, only saying it was from Yahoo Sports (claiming the author preferred to remain anonymous, or something like that). I couldn't find the article myself, so who only knows if it's real; I just thought the rumor was worth mentioning.
Is this even a possible mid-season move.. I don't think the Swedish league and his club would like this rumour very much.. Also why would he be eager to return to be the backup already this season? His Swedish team is the front-runner for the SEL trophy and he's a crucial part in their success.
I do think however that he can one day be a fine NHL goaltender, so Wings should definitely stay in touch.
