He's allegedly in rehab.
Call up Ribiero?
Either some forwards are going to have to play center (Wilson?) or they'll have to call up Kamenev or some other AHLer. Lines are going to look like a trainwreck either way.
Edit: On The Forecheck (the Preds' SBNation blog) came up with this
Aberg - Forsberg - Arvy
Sissons - Jarnkrok - Smith/Harry Z
Wilson - Kamenev - Neal
McLeod - Watson - Salomaki
Probably the best that the team can manage assuming Fisher doesn't play.
