The Leafs have sent Antoine Bibeau to the Marlies and called up Jhonas Enroth.
The Marlies play Saturday and Sunday, while the Leafs play Saturday and Monday. This move can get Bibeau into a game on the weekend, since Frederik Andersen will likely start both Leafs games.
The timing of this is complicated by the Christmas season roster freeze which is written into the CBA. The Holiday Roster Freeze begins Monday, December 19 at midnight. It applies to everyone on the NHL roster and prevents most demotions to the AHL between then and December 28.
