I read something somewhere that the rules of the suspension say that he can't play in any other pro league during the suspension.
Actually, what I've been reading is a little different. I've read that his contract with the Fins prohibits him playing for another league. However if the team wants to let him play for 1 season, they can waive this clause. Obviously playing is good for Ricky and maybe the team since it keeps him in shape. Not playing is also good for the team since there is much less injury risk.
