Preston are hoping long-term injury victim Youl Mawene will play again this season.
The Frenchman sustained serious damage to his knee during pre-season and he was not expected to feature at all this term, with damage to both his medial and cruciate ligaments.
However, Mawene has this week returned to light training - which has given North End hope that he could feature in the league before the season is out.
"He is a top pro and he has worked as hard as anyone to get himself right," said manager Paul Simpson.
"It will be a real big bonus if we have got him available to us before the end of the season.
"Basically now he has to carry on with all of the football training that he is doing and making sure he gets full power back into his quads.
"We have done some video analysis of him and identified a weakness in his quads and we need to build them up which will obviously help him when he gets back into full-time training."
The club are also looking to welcome back Patrick Agyemang in the coming weeks. The former Milton Keynes Dons forward has been sidelined since the beginning of December with a hip problem.
"Patrick has been back in full training but he will have an injection on Tuesday, aided by an ultrasound scan, so we can make sure it gets put in the right place," said Simpson.
"He will then have a couple of days out but by next week we expect him to be in full training and be available for playing."
