Port Vale could be without up to half a dozen players for the game against Mansfield on Saturday.
David Amoo, Rhys Browne, Tom Conlon, Manny Oyeleke, James Gibbons and Callum Evans are all in the treatment room.
Oyeleke is still a week away from a return but stepped up his rehabilitation at St George's Park this week.
And scans have revealed midfielder Tom Conlon has damaged medial knee ligaments.
Manager John Askey says he doesn't need an operation but is likely to be missing for a few weeks.
