Goalkeeper Alex Cisak suffered a dead leg in Sunday's first leg defeat against Boro, but he was back in training on Thursday and is expected to start.
A bug has affected some members of the Stanley squad this week but Coleman has reported a clean bill of health as his side look to battle back from 2-0 down.
Ian Craney returned for the first leg after recovering from a hamstring problem and although the midfielder did not complete the full 90 minutes, he is in contention once again.

Stevenage boss Graham Westley will leave it as late as possible before naming his side with several unnamed players carrying knocks.
Boro will definitely be without midfielder John Mousinho and defender Luke Foster, with both players still suspended.
Westley will monitor the fitness of several players in training ahead of the game, but refused to reveal which members of his squad are battling to be fit.
Midfielder Lawrie Wilson came through the full 90 minutes of the 2-0 first-leg victory over Stanley after shaking off a knock and Westley will be hoping he is available for the trip to Lancashire.
Forward Yemi Odubade will come into contention after returning from a loan spell at Blue Square Bet Premier side Newport.
