According to TSN. He's got no offers or anything but is hoping someone will invite him to training camp.
I loved the guy as a Flame and some of my best memories as a Flames fan involves Fleury, but this is ridiculous. The dude is 41 years old and the last time he saw NHL action was 6 years ago as a Blackhawk. The last competitive hockey he played was in Ireland as a Belfast Giant in 05/06. On top of all that, he's still under "indefinite suspension" in the NHL due to his struggles with substance abuse previously.
I don't know what's sparked this un-retirement and I honestly hope for the best for the guy. That said, I dont think he has a snowballs chance in hell.
