Adomah had his nose broken during the 1-1 draw with Macclesfield a fortnight ago and was restricted to a place on the bench against Bradford last Saturday.
However, after having the fracture re-set this week, he should resume his place on the right wing as Ian Hendon's side look to leapfrog their opponents.
Australian defender Daniel Leach has recovered from both the ankle injury which has sidelined him since August and the bout of food poisoning which kept him out of the Bradford draw.
He is available as his veteran striker Paul Furlong who will return up front after serving a one-match suspension.
Assistant manager Gary Breen has also returned to training for the first time since picking up a knee injury in pre-season.
