There was some bad news to come out of Preston's 1-0 loss to Newcastle on Monday with the injury to Youl Mawene.
The 30-year old defender sustained medial ligament damage after a collision with goalkeeper and teammate Andy Lonergan on the stroke of half-time.
"Youl has a knee injury which we fear might be quite bad," said North End boss Alan Irvine.
"There was a little nudge from their striker (Marlon Harewood) and a collision with Lonners, but those sort of things happen.
"Callum Davidson also felt his hamstring go tight and we had to bring him off too.
"That happened right before they scored the goal and that certainly didn't help us."
