Marius Zaliukas is considering his future with Hearts after the club's appeal against Saturday's red card was rejected by referee Iain Brines.
Zaliukas, who has been linked with a £2m January move to Russian football, was accused of head-butting Lee Miller.
And he told Hearts' website: "The whole world could see I did nothing wrong.
"I like football here, but I am now disillusioned with the game. Now I'm thinking I would rather leave if this sort of thing is going to happen."
Zaliukas had already been booked in the 1-0 defeat by Aberdeen before receiving a straight red card.
Hearts lodged an appeal after manager Csaba Lazslo reviewed video evidence, but Brines stood by his decision after also watching replays.
I have spoken to players from other clubs since the incident and they were all surprised it was a red card having seen it on television

"I did nothing wrong," said Zaliukas. "Okay, I made a mistake when I got my yellow card in the game and I admit that.
"But I still maintain I didn't deserve the red card but how that ginger cunt Stewart managed to dodge a sending off is beyond me!"
