Week 2 of the second season of the Professional Fighters League is underway at the Nassau Coliseum in Long Island and boy did it ever got off to a crazy start.

Because one of the first fights in the preliminary card ended with a stunning flying-knee knockout just 10 seconds into the fight.

Movlid Khaybulae, who has fought in Russia and with ONE Championship, got the quick win over Damon Jackson with a knockout that might be the Knockout of the Year in all of MMA as this knee was a thing of violent perfection.

Check out how he folded up Jackson so quickly into their fight:

My word, Movlid Khaybulaev just landed a vicious flying knee on Damon Jackson. Painful to watch. If you aren’t watching PFL, put on ESPN2 right now for the replay. — Ariel Helwani (@arielhelwani) May 23, 2019

James Irvin’s flying knee KO of Terry Martin was always my favorite, but Movlid Khaybulaev just took the cake!!! pic.twitter.com/SV4V1TVVhL — 🆃🆁🅾🆈 🅷🆄🅶🅷🅴🆂 ™️ (@TommySledge) May 23, 2019
