Weiss is going down to gr for a conditioning stint, still haven't heard if datsyuk good to go.
And we have a game tomorrow, someone's coming up, right?
No. Weiss still needs to be on the Red Wings roster to do his conditioning assignment. In order to activate him from IR they need the spot and the cap space, as both will still count against the Wings while he's in GR. Since they started the season with Datsyuk (and then Franzen) on IR they didn't need to send Nestrasil back down, but now that Weiss is healthy they need his spot. They'll likely just play with one fewer guy in the press box for the game (or two) that Weiss is in GR. There really is no big secret here. Nestrasil waived, and Weiss activated after Nestrasil clears.
