The position of goalkeeper will be the biggest headache for Coventry City manager Aidy Boothroyd and Doncaster Rovers boss Sean O'Driscoll when the sides meet at the Keepmoat Stadium tonight at 7.45pm.
City lost Keiren Westwood to an injury and his under-study Danny Ireland also pulled up injured during Saturday's 4-1 defeat to Bristol City.
If neither keeper is fit enough to play, Michael Quirke, who made his first team debut against Watford when he came on for the injured Iain Turner, could be back from a loan at Nuneaton or if owners SISU come up with some cash, a new keeper could be brought in on loan.
Doncaster also have custodian problems. Number one choice keeper Neil Sullivan is out with a shin injury and despite having an injection, it will be another five days before the Scot, famed for being beaten from long distance by David Beckham and David Bell, returns to training.
O'Driscoll must decide if he is going to stick with youngster Gary Woods, who let in five goals at Leeds on Saturday or give a start to loan signing Ben Alnwick.
City's leading scorer Marlon King starts his four game ban but Martin Cranie returns from his one game ban.
James Hayter and James Coppinger could return for Rovers.
