The left-back has recovered from a hamstring injury and could return to the team.
Shaun Hutchinson (hamstring), Esteban Casagolda and Marc Fitzpatrick (both knee) remain out but should all return in a couple of weeks.

But Michael Higdon could make only his second appearance of the season after recovering from a groin injury and taking part in a practice match this week.
