Striker Andy Williams has undergone a scan after being forced off with a muscle injury in Saturday’s game at Walsall.
“Andy went for a scan on Tuesday and we will assess him from there,” said boss Keith Curle.
“He is a quick healer and hasn’t had a muscular injury this season but we will have to look at the extent of the injury when we get the scan results.
“Macca (Alan McCormack) is having his first full week of training and we will monitor how he responds to that throughout the week.
“James Olayinka is continuing to have extensive treatment here and at Arsenal and is making excellent progress.”
