Seemingly in disrepair when David Moyes took over following the sacking of Slaven Bilic, the Hammers have put together an impressive run of form, despite their mediocre 0-0 FA Cup draw with Shrewsbury Town last time out.
Prior to that encounter, the Hammers drew 1-1 with bitter rivals Tottenham at Wembley, and will hope for a repeat performance this time out against David Wagner's sprightly Terriers.
WEST HAM INJURIES
Winston Reid is a major doubt for the encounter after sustaining a groin injury in the 0-0 draw with Shrewsbury at the weekend, but Marko Arnautovic is set to play after overcoming a tight hamstring.
Michail Antonio, too, could play a cameo role following a groin problem of his own. Aaron Cresswell, however, remains a doubt owing to a back problem.
Diafra Sakho, James Collins, Sam Byram and Jose Fonte are all set to miss out.
WEST HAM SUSPENSIONS
West Ham have no suspended players.
WEST HAM STARTING LINE-UP
Moyes picked a strong team for his side's encounter with Shrewsbury, and was given little in return as the Hammers huffed and puffed and were perhaps outplayed by their lower-league opposition.
Adrian is likely to return in goal, despite Joe Hart captaining the side and keeping a clean sheet against his former employers, while Mark Noble should play in midfield after being rested at the weekend.
Manuel Lanzini, too, will return to the fold, though Winston Reid's injury may force Moyes into a return to a 4-4-2 formation, with potential replacement James Collins also crocked.
Below is a possible XI for the Hammers.
