Player Knocks out Referee

This has to be one of the Most terrifying scenes in the game of Football!! Reports say During the match between Ferro and Tiro Federal in the Argentine second division a player Alejandro Roncaglia,knocked out a referee Arnaldo Beron when he was shown a yellow card.The video which has gone viral shows Alejandro give a Punch to the Referee who slumps to the ground.The match was said to be abandoned as the referee was taken to Hospital.....In my Opinion that player should be saying Bye-Bye to his football career!!!
