The Valiants are waiting on news of the extent of Jack Grimmer’s injury after the loanee was stretchered off during the 3-1 defeat to Crewe.
Grimmer has been impressive since joining on loan from Fulham but he could be set for a lengthy spell on the sidelines.
Manager Micky Adams commented: “We don’t think it is knee ligaments, it is probably his thigh. But it is too early to talk about that.”
If Grimmer is ruled out of action, Vale have a number of options at the back. Carl Dickinson could move into the centre to partner Joe Davis. That would allow Dan Jones to move to the left-back position.
However, Vale also have Richard Duffy and Liam Chilvers available again after they recovered from injuries while out-of-favour Chris Robertson is another option.
