The midfielder went down under pressure from Mohamed Diomande before referee Willie Collum pointed to the spot.
Celtic star Matt O'Riley has been accused of a "theatrical" dive to earn his side a penalty against Rangers.
He said: "You know what, you are a huge advocate of the Simulation Game - but you're commentary when the Celtic player went over in the box you are screaming for a penalty. It's never a penalty - it's for the Simulation Game surely?" "It's a beautiful touch from Matt O'Riley by the way to take him out. But has he brings his leg through, he kicks Diomande's foot. That's not what bring him down; there's another step because he's felt the contact and then he's thrown himself over. It's a bit theatrical.
