Early in the second half of an Argentine second division match between Boca Unidos and Gimnasia, the referee was hit square in the chest with a rock thrown from the stands. Trailing 1-0 to the visiting Gimnasia, Boca Unidos fans were angered further by the referee's decision to show one of their players a red card.
As the ref fended off verbal challenges to his decision from other players, a good sized rock hit him in the left pec and he then slumped to the ground. After getting checked out, the referee did continue and later sent off two Gimnasia players. Gimnasia still won 1-0, though.
This has been the Dirty Tackle of the Day: a chronicling of unfortunate events.
