Hearts boss Csaba Laszlo was left bemused after Lee Wallace was sent off after the final whistle following a skirmish in the tunnel.
Hearts had just lost 1-0 at Aberdeen ending their seven game unbeaten run.
After the ill-tempered game, Laszlo said: "I don't think I will be punishing either of the players who were shown red cards. There is a lot of emotion involved in the job of a footballer.
"We just have to concentrate on the next game now. I don't know really know what happened with Lee Wallace. After the game the referee came into the dressing room and had a conversation with Lee and after that he came up to me and told me had given him a red card."
Laszlo was also at a loss to explain the ordering off of Zaliukas.
He joked: "I think Zaliukas must have been fighting with Christian Nade because they were both shown cards but the Aberdeen player was not, although I didn't ask the referee about that one."
