Ullstrom up, Rolston waived

The Islanders announced that, first reported by Arthur Staple, a few minutes ago.

As Bob McKenzie reminds us, it’s an important waivers day: A regular roster NHL player, if he isn’t technically on an AHL roster on Monday at 3 p.m., can’t be sent down for the rest of the year. So, if teams want the flexibility to move out a veteran at any point the rest of the year, he’s got to go on waivers today. (He reports that these guys are on waivers today. For instance, if I’m not mistaken, the absence of Dylan Reese from that list makes him an NHLer for the rest of the season.)

More but less pressingly is what that means for the Sound Tigers’ lineup tonight, which is to be seen. They played their only 12 available forwards last night. If Calvin de Haan is indeed available, they could go 11 forwards/seven defensemen.

Edit: ECHL transactions have Greenville loaning Marc-Olivier Vallerand to Bridgeport.
