Robbie Neilson last night hammered referee David Munro over the decision to send him to the stands at Tynecastle.
The Hearts boss was ejected from the dugout for the final four minutes of the match after being shown a second yellow card by the whistler.
It meant a nervy final period for Neilson who watched his side hang on to see out a 1-0 victory over a hardy St Mirren.
