Leafs have to waive the players by noon today if they require them in order to be cut and to be sent down. So for players like Leivo, Marincin, Fehr, Moore, etc, if they aren't on waivers by noon today, they are likely here to stay barring a trade out of the team of course.
Liljegren will very likely be loaned to Sweden or at the very least assigned to the Marlies. Polak doesn't have a contract and doesn't require waivers or a release.
So the Leafs are really at 24 players, which means they have to send down a player by tomorrow. I'd probably bet it being Borgman, but it's possible there's a small injury which opens up a spot in the mean time. It's possible a trade is in the works as well but seems unlikely.
