Gilbert Yvel has retired after 16 years of fighting, so let’s watch one of his most famous KOs.

Gilbert Yvel may be known anonymously as the guy who knocked out the referee on so many viral videos showing crazy shit going down, but he also gave his life to the sport we love. His run in Pride was underwhelming, and it’s actually pretty crazy to look back on his 12 fights in the UFC and Pride and see that he only walked away with two wins. One of which was this knockout of a prime Gary Goodridge. Brutal.
