Former top flight official Dermot Gallagher believes Ross County star Kayne Ramsay was unlucky to see red for his crunching tackle on Tom Rogic.
But he was full of praise for Bobby Madden's decision to award Rangers a spot kick in their Sunday clash with Dundee at Dens Park.
Gallagher admits Rogic's subsequent injury adds a caveat to Ramsay's red, however, he believes it wasn't an open and shut case to send him off against Celtic.
