This is really not surprising at all. AA has waiver exemption and while his game has been energizing and fun to watch, he's not setting the world on fire with his play. Of course, if we had the room for another young guy with plenty of scoring upside, I'd prefer for him to stay up. ...but until we shed some excess forwards it's back to GR.
A lot of speculation on injury (nagging back issues) and whether the Wings are trying to use some magical loophole to avoid waiving Jurco. Fact is, even on a conditioning stint he counts as a roster player -- so that's not the case.
If it is a nagging back issue, Ultimately I think it's to get Jurco back into game situations. The guy's been practicing with the Wings, but that's not the same as ice time.
14-Days isn't going to be enough to turn around his play, but it could be enough to at least get it jump-started.
