There's a growing injury crisis at Finn Park after three players suffered injury in Friday night's defeat at Cork City.
Harps lost 3-1 at Turner's Cross, conceding the first two goals in the opening seven minutes.
They then lost Raymond Foy and Adam Hanlon to injury before goalkeeper Richard Brush was forced off in the second half.
Harps were 3-0 down going into the closing stages when Ryan Curran scored a late consolation.
Ollie Horgan's side now face Wexford Youths away from home on Friday night.
