Exeter boss Paul Tisdale bemoaned his side's bad luck with penalty decisions as they slipped to a 2-0 defeat at Huddersfield.
Striker Daniel Nardiello went down in the box under challenge from Jack Hunt in the second half but no penalty was given.
Tisdale said: "That's the second or third we've had in successive games with nothing given.
"I was 60 yards away so I can't be sure but Daniel said we were hard done by again. He is not the kind of player to go down if he has a shooting chance."
Goals from Jamie McCombe and Jordan Rhodes sealed Town's win.
