Dundee United player-manager Craig Brewster was more annoyed by Barry Robson's red card than a late Hearts penalty as the sides drew 1-1.
"Barry was strong to hold the ball up and, although he just knocked it a touch in front of himself, he tried his best to retrieve it," said Brewster.
"In doing so, he fouled Steven Pressley and got a straight red card, which I thought was extremely harsh.
"But I have told the players that I thought they were immense."
