With the Copa America quarter-final between Chile and Uruguay evenly poised at 0-0, Jara decided to niggle Cavani by sticking a finger in his backside.
The Uruguayan ace reacted with shock which saw Jara flop to the ground, grabbing his face like he had been struck.
After seeing the incident out of the corner of his eye, the referee gives Cavani his marching orders for violent conduct.
18 minutes later, Chile score the only goal of the game to qualify for the Copa America semi-finals.
Genius?
