Midfielder Arfield and winger Carey missed last week's draw with Bournemouth as they were on international duty for Scotland and Republic of Ireland Under-21s respectively.
Both players are expected to return to the Terriers' bench. Goalkeeper Alex Smithies, an unused substitute for England Under-21s, will retain his place in the starting line-up.
But Town will be without defender Gary Naysmith again as the Scotland international has had surgery on his foot and will be sidelined for four months, so Liam Ridehalgh will continue at left-back.
Nathan and Tom Clarke remain sidelined with respective knee injuries. Nathan is expected back in full training within four weeks, while Tom has targeted a return to action at Christmas.
