Midfielder Tommy Miller is a major doubt ahead of Saturday's play-off semi-final first leg against West Ham. Miller sustained a badly bruised foot during Sunday's 1-1 draw with Cardiff.
Boss Joe Royle told the club site: "Tommy's foot is swollen quite badly and we will have to see what the scans show.
"At the moment he has to be considered a doubt for Saturday's game.”
Better news is that Spanish striker Pablo Couñago is back in full training after his hamstring and groin injuries.
