Layton Maxwell was also thought to have a hernia but it's been found to be just a stomach strain. Rest will cure him.
The absence of Campbell and Leo, who was injured at Huddersfield last week, means that Gavin Gordon could expect to be part of the squad for a few weeks. Gordon took his chance in the FAW win last week, scoring two goals and despite being booked in the 5 mins he had on the pitch v Oldham last night I thought he showed positive body language when he came on.
