Speaking to the official club website, former Manchester City, Oldham and Everton boss Royle said: “We have a few in for treatment and they probably won’t train until Thursday.
“Jim is in a bad way but knowing him, we will be able to wheel him out there on a life support machine and he’ll play.
“Jim won’t want to miss this one. It’s massive game for both clubs. If we win, it will leave us in a decent position for the last game of the season at home to Cardiff and will virtually put Sheffield out of the Play-Offs at the same time.”
