Scunthorpe will make a late decision on leading scorer Gary Hooper ahead of their crunch clash with bottom-of-the-table Peterborough.
The former Southend striker has missed the last three games with a groin injury and was unable to train again on Monday but boss Nigel Adkins will monitor his fitness on the day of the game.
If Hooper, who will have an injection on Wednesday, is ruled out then Adkins could play winger Garry Thompson alongside Paul Hayes in attack once again after he scored in Saturday's win against Plymouth.
Midfielder Josh Wright did not feature against the Pilgrims due to a bruised toe and it is not yet known how long he will be out for.
Defenders David Mirfin and Marcus Williams recovered from groin injuries to play at the weekend and came through the game unscathed.
Skipper Cliff Byrne serves the third game of a five-match suspension, while Ian Morris (knee) also remains on the sidelines.
Peterborough boss Jim Gannon has defensive problems ahead of the trip.
Wales international centre-half Craig Morgan missed the 1-0 defeat at Nottingham Forest on Saturday with an ankle injury and is still struggling so on-loan Wolves right-back Mark Little will continue to fill in.
Record signing Ryan Bennett is another defensive casualty as he recovers from an ankle injury of his own so Gabriel Zakuani will play alongside Little.
Midfielder Lee Frecklington is out with a knee injury while strikers Izale McLeod and Aaron Mclean are also sidelined with knee injuries.
Gannon's side have lost their last two games to slip 10 points adrift of safety and have eight games remaining to stage a remarkable escape.
