A pickleball tournament in Mexico has gone viral after a vicious kick to the head soured the end of a championship game.

A video circulating the internet shows the moment a beaten finalist lands a brutal kick to the head of his victorious, and exuberant opponent.

Peter Shonk shared the video of himself being the recipient of the head kick following his, and Sylvain Bouchard's victory in the Men's Advance section of the Quintana Roo International at the Pickleball Club Playa Del Carmen.

The incident came following championship point, according to US-based pickleball news source, The Kitchen Pickleball.

An exuberant Shonk screams, swears, and appears to knock the paddle out of an opponent's hand as they meet at the net to shake hands.

Shonk bends over the net, appearing to pick up the paddle he knocked from his opponent.

However, the beaten finalist was not thrilled with the victor's reaction and proceeded to land a head kick that belonged in a ring rather than a court.

Shonk collapsed to the ground after the kick, however, was reportedly doing fine after the blow.

"It occurred after championship point from a tournament this weekend and the man that was assaulted, Peter Shonk, shared this video with us to post and wants everyone to know that he is ok," The Kitchen Pickleball reported. 

"This behaviour is disgusting and completely unacceptable."
