St Mirren fail to overturn Marc McAusland red card
St Mirren have lost their appeal against the red card defender Marc McAusland picked up during last week's 2-1 defeat at Hearts.
McAusland was sent off for denying Dale Carrick a goalscoring opportunity, with Jamie Hamill converting the penalty.
The club's decision to contest the ruling allowed him to feature in Sunday's 1-0 loss at Celtic.
The 25-year-old will now sit out the Premiership game at home to Aberdeen on 15 February.
