St Johnstone appeal diving yellow cards handed to Graham Cummins and Chris Kane
Both players were cautioned for simulation by referee John Beaton during Saints' 1-0 victory over Hearts on Saturday.
St Johnstone will discover on Thursday if they have been successful with their appeals against bookings handed to Graham Cummins and Chris Kane for diving.
Both players were cautioned for simulation by referee John Beaton during Saints' 1-0 victory over Hearts on Saturday.
Cummins - who scored the Perth side's second-half winner - was accused of taking a tumble following a challenge by Igor Rossi 14 minutes in, while substitute Kane was also shown yellow late in the game after hitting the deck.
But McDiarmid Park boss Tommy Wright has decided to challenge the decisions after reviewing footage of both incidents.
The cases will be heard by the Scottish Football Association's judicial panel on Thursday and Wright will hope his players get the same outcome as Jambos frontman Tony Watt, who had the booking he received against Hamilton last week wiped on appeal.
In a statement posted on the club's official website, Wright said: "We've viewed the footage of the incidents and having lodged our notice of our intention to appeal yesterday are making a full submission to the SFA today.
"We fully support the game's authorities as they attempt to clamp down on this aspect of the game but in both these cases we feel that the players have been wrongly cautioned.''
Wright had warned his side to be on the guard against Robbie Neilson's Gorgie men before the match after claiming Hearts had "maximised'' a number of penalty claims to their advantage already this season.
But he warned that if any of his own players were found to have gone to ground without cause he would punish them himself.
Speaking after the Hearts victory, he said: "I'm going to look at it and if I think the decisions are right the players will be fined and a line will be drawn under it.
"It's not something we advocate, it's not something I advocate. That's how we'll deal with it, because I don't want it in the game.''
