The TSN article specifically stated that Michalek currently is the only one not locked out. Must have something to do with the timing of the surgery.
Find it odd that in another thread there was a translation about how he was feeling good /had a good contract and didn't want to risk it in a czech league.
There was speculation during the last lockout that some players opted for surgery rather than continue with rehab because it meant they would get paid during the lockout. The Leafs paid Mogilny and Belfour for the entire lockout last time around. As long as the injury is hockey related, the player gets paid.
The reason Michalek doesn't want to risk his contract by going to Europe is that any player who goes over there during a lockout has to pay for their own insurance. With Michalek's injury history, he'd probably be paying a lot, adn if he gets injured over there, his NHL contract could be voided.
That's why Crosby probably won't be playing hockey anywhere during the lockout. With his scrambled brains, he will pay a fortune in insurance, if he can get any at all, and #2, that's a huge contract to risk just to play in Europe.
