Iain Turner and Chris Brown are set to give Preston boss Phil Brown a double boost ahead of the trip to Doncaster.
Everton goalkeeper Turner, who initially arrived at Deepdale in February, has extended his emergency loan until the end of the season.
The Scot has missed just one fixture through injury since his arrival and should line up between the posts at the Keepmoat Stadium.
Striker Brown is set to come back into contention after injury but Conor McLaughlin is out for the season with a long-term ankle injury and David Gray is still on crutches after taking a knock to his shin at Norwich last month.
Defenders Leon Cort and Sean St Ledger also look set to remain sidelined.
