Blues duo Gassan Ahadme and Greg Leigh have been back in training this week following their injuries.
Striker Ahadme, who turned 22 yesterday, picked up a foot injury in the Plymouth game at the end of September, while left-back Leigh suffered a compressed fracture to his leg at Sheffield Wednesday the previous week.
Manager Kieran McKenna says that the duo progressed to training alongside their teammates a couple of days ago.
"Not a full week with the group,” he said. "[Gassan] and Greg joined in with the group on Wednesday, so that was a big positive. And, of course, [Gassan] had his birthday on Thursday.
"He trained well on Wednesday and straight away he showed his hunger and his attributes that he’s going to hopefully bring to the team, and it’s good to have him and Greg back in training.”
Quizzed on when they might be available for match action, McKenna added: "Let’s see how their progress comes. Of course, this weekend is too soon for either of them to start.
"Gassan is ineligible for Tuesday night [the Papa Johns Trophy tie against Portsmouth], so after this weekend he’s got a good week to focus on the Buxton game and try and make himself available for that one. And let’s see how Greg responds in training.”
Sone Aluko, Lee Evans, Dominic Ball (all knee) and Tyreece John-Jules (hamstring) are all sidelined at present.
