Hearts are set to lodge an appeal after winger Alan Forrest was booked for simulation during Saturday's clash against Ross County.
The former Livingston man was denied a penalty by referee Alan Muir and the whistler deemed the incident to be simulation.
SFA disciplinary rules allow for yellow cards for simulation to be appealed and Hearts are now set to put a case forward for their player after viewing the penalty call again.
Steven Naismith was furious at full-time as he slammed the decision.
He explained: "There is contact on Al Forrest. Now, I get the referee not seeing it with the speed of play, but VAR has got to see it.
"I have come in and looked at it and there is contact. If you pause it, there is contact, but it’s not given. It’s not good enough.
"There is contact, which means it’s a penalty. We might get an apology, Al might get his yellow card rescinded but I’m not sure he’s going to get enough [bookings] to get a suspension. It’s just really frustrating."
