Boss Mark Robins is hopeful Sharps' groin strain will have recovered in time, but has more worry over Jamie Green's ankle injury sustained in the same game.
The players have an extra day to recover with the game being put back a day to Sunday, due to the U2 concert tonight.
Meanwhile Micky Cummins, Marc Joseph and Steven Brogan all had run outs in a practice match victory over Barnsley yesterday. Ryan Taylor netted all the Millers goals in the 4-3 win.
