Bo Nickal’s undefeated run in the UFC came to a crushing end courtesy of a Reiner de Ridder knee to the liver in the second round of Saturday night’s UFC Des Moines event.

In a stunning upset at UFC Des Moines, Reinier de Ridder handed Bo Nickal his first professional MMA loss with a brutal TKO victory in the co-main event. De Ridder's well-balanced attack and superior striking proved too much for Nickal, as he delivered a devastating knee to the body that forced the stoppage at 1:53 of the second round.
