His face shield came down when Pisani hit him and cut him on the nose. It was a far worse looking injury than it actually was--though Pisani deserved the boot.
I'm more concerned about Hahl's shoulder injury. McAllister's injury doesn't bother me as much--he's not one of my favorites anyway. But Hahl was really coming into his own--showing some versatility playing both 3rd line LW and 4th line center. We will miss his speed if he's out for an extended period of time.
If he is out, it'll probably mean yet another call-up from the red-hot (and unbeaten, yo) Hershey Bears. I'm betting if Riku can't go, they'll send up Krestanovich or Moore.
