Theo Robinson could return to contention after being omitted last week due to disciplinary reasons.
Australian defender Heffernan, on-loan Preston centre-half Trotman and striker Eccleston, on loan from Liverpool, all made their first appearances for the Terriers at Yeovil.
Eccleston, who scored the winner on his debut, was forced off with a gashed knee, which later required stitches, but he is expected to be available as Clark's play-off chasing side look to extend their unbeaten league run to five matches.
