DEAN Morgan's hamstring injury reared its head again as he lasted barely half an hour of Wanderers' draw against Fleetwood.
The striker played the full 90 minutes against Accrington Stanley on Saturday but he broke down before half time last night.
Blues boss Gareth Ainsworth is hopeful it's not a tear of the muscle, after his top scorer missed six weeks of action with a previous injury.
He said: "His hamstring's tweaked again, which isn't great. He's done all his rehab, he's done everything he could but unfortunately his hamstring seems to have cramped up again, or tweaked. We hope it's just a fascial tear and not the muscle itself."
Fellow striker Jon-Paul Pittman is now back in training after being sidelined for ten weeks with a knee injury and Ainsworth said: "JP will definitely be in my thoughts for the weekend."
