Liam Bridcutt starts a two-match ban after collecting his 10th yellow card of the season at Cardiff on Tuesday night, and Dean Hammond is an injury doubt after limping out of the 2-0 win.
"We knew it would only be a matter of time until Liam got suspended," said first-team coach Charlie Oatway.
"It's a shame that two of our more holding midfielders could be out at the same time but we are hoping that Deano will be okay. We will do some checks during the week."
Oatway also confirmed that striker Craig Mackail-Smith was left out at Cardiff as a precaution.
"Craig has a niggle which we didn't want to push with a long journey," he added.
"He would stiffen up on the way home so the medical staff took the decision out of his hands to make sure he gets an extra couple of days rest."
