On-loan Manchester United midfielder Danny Drinkwater and in-form striker Theo Robinson are in the frame to return having recovered from groin and ankle injuries respectively.
Clark is also boosted by the return of winger Gary Roberts, who has completed his three-match suspension.
Robbie Simpson is also in contention to start after scoring his first goal for the club in the Terriers' 2-1 triumph over Rotherham in the Johnstone Paint Trophy in midweek and he could be given the nod ahead of Jordan Rhodes.
Clark's only absentee is utility player Tom Clarke, who is on the sidelines recuperating from knee surgery.
Success at stadium:mk would see Clark's men leapfrog their hosts into third place in the table.
