Scunthorpe are sweating on the fitness of Sam Johnstone.
The goalkeeper, on-loan from Manchester United, missed Saturday's goalless draw with MK Dons due to a dislocated finger and assistant manager Chris Brass confirmed the 18-year-old will be assessed before being included in the squad to face the Terriers.
"We've got to wait on what the medical people say before we an make a decision," Brass told the club's official website.
If Johnstone is once again ruled out, Sam Slocombe is in pole position to keep hold of the number one jersey for a second successive game after keeping a clean sheet at the stadium:mk.
Midfielder Damien Mozika could also miss out after he was absent from the trip to face Karl Robinson's side due to an ankle problem.
Huddersfield will be without suspended defender Callum Woods when they bid to extend their unbeaten league run to 40 matches.
Woods picked up his fifth yellow card of the season during Saturday's home win over Preston and will serve a one-game ban, so Gary Naysmith is expected to make only his sixth start of the season at left-back.
Midfielder Oscar Gobern is struggling with a knock sustained last week in training and is still rated doubtful, but apart from goalkeeper Alex Smithies, a long-term absentee after knee surgery, manager Lee Clark has no other new injury or suspension problems.
Striker Lee Novak is hoping for a recall up front alongside Jordan Rhodes after starting the last two games on the substitutes' bench, while midfielder Donal McDermott, left out altogether in recent matches, is pressing his claim for a place in the squad.
