Dutch born Ghanaian youngster Jeremie Frimpong received his first career red card for Celtic in the old firm derby on Sunday at Hampden Park.
The Ghanaian who started his first Glasgow derby against Rangers saw red in the second half after taking down Columbia striker Alfredo Morelos in the second half for a penalty.
Christopher Jullien scored the winner with Celtic's only shot on target, though the French defender appeared a yard offside.
But three minutes later in a frantic contest, Jeremie Frimpong was sent off after fouling Alfredo Morelos in the box, only for Fraser Forster to save the Colombian's penalty.
That was only one of a series of brilliant saves by the Celtic goalkeeper, who spectacularly denied Ryan Jack before the break as well as Morelos on three occasions.
The Rangers striker wasted a number of other opportunities including one in stoppage time as, despite finding the net 25 times this season, he remains without a goal against Celtic.
