PHOTO: Gonzalo Jara gets Edinson Cavani sent off by sticking fingers in ... a sensitive area

Uruguay was going toe-to-toe with Copa America hosts Chile in their quarterfinal contest on Wednesday evening inside a raucous, hostile Estadio Nacional in Santiago.

And then it all went to hell.

Striker Edinson Cavani was shown a second yellow card in the 63rd minute after an altercation with defender Gonzalo Jara, when it looked as though the physical striker made contact with the Chilean's face.

Why was the Uruguayan striker so incensed? Was it the fact that Jara's chin was barely grazed before hitting the turf after the most delayed reaction in football history?

That would be a legitimate gripe, but no.

The real reason, you see, was that Cavani had simply been reacting to the fact that Jara got away with slyly sticking his fingers between his buttocks ...

Dude. Seriously. Gross.

Down to ten men, Uruguay would concede a late goal to lose the match 1-0, and bid farewell to the tournament.
