Yeah, he seems to be the 13th forward. If he is staying, I assume he'll rotate with Steen. I just thought it was strange that they called him up a few hours prior to game time as opposed to prior to the morning skate. That sometimes suggests there's a player ailing.
They haven't done anything with Poitras yet, he's still on the active roster. Richard, McLaughlin, Brown, Megna, Brett Harrison were basically their only options cap wise. To get anyone else up (Beecher, Markulov, Lysell, etc.) they would have to make another move, either LTIRing Poitras or waiving/demoting a player.
