Hearts manager Csaba Laszlo says he has no concerns about his team's discipline after their red card tally for the season reached seven.
Marius Zaliukas was sent off after a goalmouth tussle, while Lee Wallace was saw red after the defeat at Aberdeen.
"I don't think there is indiscipline in the squad, definitely not," Laszlo told BBC Sport.
"I'm worried they got sent off and not more. If you have red cards you must accept them and miss the next game."
Hearts lost the match at Pittodrie 1-0, ending a seven-match unbeaten run.
The dismissals mean Zaliukas and Wallace will be absent from the Hearts defence for the Edinburgh derby with Hibernian next weekend.
"I'm not disappointed with the performance, more with the result. We tried to play football," said Laslzo.
"When Zaliukas got sent off it became very difficult for us but we will learn from this game.
"We will find somebody who can play in these positions."
Wallace received his red card in the dressing room for an outburst at referee Iain Brines after the final whistle.
However, the Hearts boss was backing both defenders.
"I'm not thinking about punishing these players. They are doing a job, they have emotion," Laszlo told the Hearts website.
"They did not kick anyone in the field, but this is life."
Hearts have received the most red cards of any SPL team this season, while Hamilton and Falkirk are next with four each.
