Preston boss Billy Davies fears that midfielder Paul McKenna could add to his injury worries as the most crucial part of the season approaches.
McKenna limped out of North End's 1-0 win over Crewe that saw them open up a five-point gap over Wolves in the final play-off spot.
With just six games left to play Davies needs all hands to the pump but he will be sweating on the results of scans on McKenna, who could have torn a groin muscle.
Davies will be hoping McKenna is not as bad as feared as it would be another blow on top of the news that Callum Davidson will play no further part in their season.
Davidson damaged knee ligaments in training before Saturday's draw with Plymouth, and is set to miss out on Preston's play-off assault.
Add that to star striker David Nugent's season ending prematurely with a broken toe and Danny Dichio's injury problems and Davies has a bit of a headache to cope with as he tries to get his side into The Premiership.
Preston made the play-off final last season only to lose out to West Ham in Cardiff, and Davies admits the injury problems are worrying.
"It's very bad news about Callum," said Davies.
"We are losing key players at this stage of the season which is something we didn't do last season.
"Last year we had a clear run as we went towards the play-offs but this season fate seems to be against us. We will have to look at some of the younger players now."
