WATCH: MMA Fighter Delivers The Craziest Rolling Thunder Kick Knockout

Former Ultimate Fighting Championship star Ross Pearson received a rude welcome on his mixed martial arts return last weekend. The UFC veteran, who won The Ultimate Fighter 9, made a comeback at the MTK MMA: Probellum in London on Saturday, following a successful boxing debut last May. Standing on his way was Davy Gallon, who was dubbed as the underdog with a 17-7-2 MMA record. The welterweight pair starred in the headlining bout of the London show and MMA fans got to witness a near-perfect rolling thunder kick finish. Late in the third round, the Frenchman landed the brutal blow , leaving the former UFC star knocked out cold in the canvass. “Oh my goodness me. I don’t even know what to call that. I have never seen a finish like that,” the commentator said of the stunning finish. Gallon's rolling thunder kick knockout has since gone viral and is being considered as a strong candidate for the Knockout of the Year recognition.

"As a fan of Ross Pearson from the TUF days, that KO was hard to watch. But take a bow Davy Gallon." "That’s the KO of the year for sure. Don’t think I’ve ever seen anyone pull off a rolling thunder kick before and KO someone with it," wrote the sports journalist, Chisanga Malata. James Edwards tweeted, "Christ on a bike what a KO... this is literally in the final minute of the final round! Flying Rolling Thunder KO." "Oh shiiiiit...I did not forsee Ross Pearson being on the end of a vicious rolling thunder KO tonight!!" Michael Morgan added. Gallon secured his 18th professional victory while Pearson suffered his third straight loss since February 2018. https://twitter.com/Shaun_TRFC/status/1195835366928003072 Check out the MTK MMA: Probellum results below: Davy Gallon def.
