Former WSOF featherweight champion Georgi Karakhanyan is probably nursing a pretty bad hangover today; The Armenian-Russian was outclassed by the relatively unknown Rick Glenn. Before last night, 'Insane' was unbeaten since 2011 and was riding a nine fight unbeaten streak. He was outclassed by Glenn at WSOF 10.

'The Gladiator' was unbeaten in his last 10 in the run up to his first big time title shot, and perhaps 'Gogo' underestimated his foe last night. Glenn put on a ground striking clinic that saw the champion rooted to his stool, on the doctor's advice, after just two rounds. A knee to the body at the end of round one appeared to do the damage.

Back to the drawing board for Karakhanyan, and welcome to the title for the huge underdog Rick Glenn. World Series of Fighting put on another great show, so check out the full highlights of the featherweight title upset, courtesy of NBCsports and stay tuned to LowKick.com!
