Robbie Neilson has claimed referee Greg Aitken got the key decisions right in Hearts' win over St Mirren.
Connor Ronan was shown a straight red card for a tackle on Beni Baningime before the home side had a penalty claim ignored when striker Alex Greive tumbled in the box.
Some of the calls infuriated Neilson's counterpart Stephen Robinson, but the Jambos boss felt the referee had a good game.
