A rare double-knockout occurred during the Shamrock FC 285 event held at the Ameristar Casino in Kansas City on Saturday.
In a fight between Axel Cazares and Alan Vasquez, both fighters planted to throw right hands at the same time. Both connected flush. And both fell.
Yet it was Vasquez who was deemed the winner because he was the first to get up and clear the cobwebs.

Double knockouts are a rare thing in mixed martial arts. Perhaps the most famous instance of a double-KO occurred in 2007, when Gray Maynard and Robert Emerson at The Ultimate Fighter 5 Finale. Maynard was attempting a takedown and knocked himself out, while Emerson sustained a rib injury.
