On-loan defender Scott Wharton is a doubt for Saturday’s trip to Colchester after picking up a knock in the midweek win at Swindon.
“We gave Scott 48 hours to see how it settled down,” said boss Keith Curle.
“He’s had some treatment and we will make a late assessment on him for the weekend.
“Alan McCormack is back field based training but not with a football yet.
“Steve Arnold and Joe Martin are going to be a period of time but Reece Hall-Johnson has had some treatment and he is another one we will assess before Saturday."
