The first Glasgow derby of the new season took place on Sunday at Celtic Park.
Brendan Rodgers' Celtic went up against Rangers, now coached by Steven Gerrard, and the tackles were flying in during a goalless first-half.
Scott Brown landed a late challenge on Rangers striker early in the opening period and both sides had their fair share of fouls. However, the referee appeared to miss the most blatant foul of the day.
Celtic laid siege to Rangers' goal for most of the first half, and goalkeeper Allan McGregor was called into action several times. After making one save, the Rangers 'keeper kicked out at Kristoffer Ajer as the Celtic defender lay on the ground.
If the referee or his assistants had spotted it, Gerrard's side could very easily have been down to 10-men. The TV cameras picked up on it, and you can watch the incident here:
Former Celtic striker Chris Sutton claimed on Twitter that McGregor should have got his marching orders for the kick.
