Dundee defender Nathan Ralph has failed in his appeal against the red card he picked up against Rangers.

Referee Alan Muir sent Ralph off for a foul on winger Daniel Candeias on the edge of the box, and the Dens Park side were further punished when Rangers scored from the resulting free kick in the 1-1.

Dundee boss Jim McIntyre indicated after the game that he would challenge the decision, which was made for denying a goalscoring opportunity.

However, an independent panel reviewed the incident and supported Muir's decision, leaving Ralph to serve out a one-match ban.

He'll miss Dundee's trip to Rugby Park to face Kilmarnock.
