When the sweet sounds of Duane Eddy's 'Rebel Rouser hit the loud speakers inside of the American Airlines Arena in Dallas, Texas, that could only mean one thing - the light heavyweight debut of Nikita 'Al Capone' Kyrlov. Krylov had been given a promotion of sorts, moving from the opening fight on Fight Pass in Chicago at UFC on FOX 10 earlier this year to the opening PPV fight of tonight's UFC 171 card.His opponent would be Tennessee Volunteer Ovince St. Preux, a light heavyweight with a 7-1 record under Strikeforce and the UFC. The proven finisher upped his career total to 11 tonight with one of the most rare finishes in MMA. St. Preux was able to put Krylov away with a shoulder choke from side control, something you don't see often at the highest level of mixed martial arts. Somewhere, TUF season 2 contestant Jason Von Flue was smiling tonight.Check out the .gif below via ZombieProphet.
