Huddersfield could discover whether a trip to a London specialist this week has cured Anthony Pilkington's niggling hamstring injury.
The Terriers' nine-goal top scorer missed the midweek FA Cup win over Cambridge due to the problem and will not be risked by manager Lee Clark unless he is fully fit.
Clark said: "He's had two good sessions with an expert in that field and we'll see how he goes over the next couple of days.
"But if he isn't quite right, we won't risk him. If he does make the squad, it will be a sign that he's 100% fit again."
