M-1 may be best known as the group that manages Fedor Emelianenko. But in an M-1 Challenge event in 2009, Rustam Khabilov earned a great knockout victory.
Khabilov and Akin Duran basically circle each other waiting for the first strike. Khabilov quickly begins his attack throwing a one-two combination and then grabbing the Turkish Duran. Khabilov then picks up Duran and suplexes him.
The ensuing suplex knocks Duran out cold and Khabilov gets one more shot in before the ref comes over and stops the fight.
The official time of the fight was eight seconds long according to Sherdog.com.
Khabilov after this fight has gone 5-1 to improve his overall record to 11-1 in his career. Khabilov most recently fought Ruslan Khaskhanov, but lost via split decision in February of this year.
Duran on the other hand is 3-2 in his career and has not fought in MMA since his loss to Khabilov in August of 2009.
