Darren Carter is Preston's major injury concern for their home game with Scunthorpe.
The midfielder sustained an ankle problem in the 3-1 defeat to Crystal Palace and it is doubtful he will be fit for the crucial game with the Iron.
Winger Chris Sedgwick is still sidelined with a knee injury, although it is hoped he might return for the Coventry game next week.
With Sedgwick out, Keith Treacy will continue to deputise and will be eager to further show manager Darren Ferguson his worth to the side.
Treacy is the only out-and-out winger at Ferguson's disposal as Ross Wallace is unavailable as he completes his two-match suspension.
Paul Parry and Barry Nicholson remain sidelined after long injury lay-offs, although Nicholson has returned to light training.
Scunthorpe manager Nigel Adkins welcomes back leading scorer Gary Hooper and defender David Mirfin.
Striker Hooper has been sidelined for four weeks with a groin injury while Mirfin has missed the last two games with a calf problem.
Midfielder Sam Togwell (groin) is still two or three weeks away from fitness, though, while Marcus Williams is a doubt after being taken off against Swansea due to illness.
Scunthorpe will be desperate for a win as they battle to avoid relegation and Adkins is delighted to have Hooper back for the run in.
"I think it`s fair to say he (Hooper) and Paul Hayes have been fantastic for us this season and I would like to think they will be firing on all cylinders on Saturday," he told the club`s official website.
"We are going to Preston with key players returning, a positive attitude and as a united group determined to get three points."
