The former Hartlepool man has been suffering with injury over the past few days, and will have a fitness test on Friday to determine if he should be added to the squad or not.
Pablo Counago, Chris Bart-Williams and Chris Makin are the only other players ruled out through injury allowing Royle a bigger pool of players than usual to pick from.
Full Squad: Bent, Bowditch, Davis, Diallo, Elliott, Kuqi, Magilton, McGreal, Naylor, Price, Reuser, Richards, Santos, Westlake, Wilnis, Wright.
