The goalscorer is pretty excited, as soccer goal scorers tend to be. This one runs around until he come upon the dugout that protects the bench players. He leans forward and throws his head into the side of it ... and his head-butt smashes right through the dugout!
Well, destroying the dugout is a no-no. And our overly excited goalscorer is shown a red card, resulting in his expulsion from the match.
