St Mirren earned their first win of the season after coming from behind to win 3-2 over Aberdeen.
In 20 games under manager Stephen Glass, Aberdeen have now kept just one clean sheet.
"I thought we were okay up until the red card. Lost a couple of poor goals after it, and a poor one in the first half, that's it in a nutshell I think," said Glass after the game.
"I agree it's a red card. It's not something Teddy Jenks has meant to do, but it is a second yellow card."
St Mirren boss Jim Goodwin was upbeat.
"There's no getting away that the sending off is a major turning point in the game," he said. "But I have to give credit to my players for moving the ball from side to side and creating those gaps."
