Beknaz Almazbekov, Galatasaray's 13-year-old captain, dribbled inside from the left and fell down under pressure from an Istanbulspor defender in the box.
The referee gave a penalty, but Almazbekov disagreed.
With his team already winning 1-0, he rejected the opportunity to double their lead and intentionally kicked the ball out of play.
Almazbekov's side went on to beat Istanbulspor 3-0.
