Tatsuya Mizuno did his best to stick and move. Instead, he got stuck.
Flat-footed as he may be, Russian slugger Sergei Kharitonov still packs knockout power, and he flexed it early in the first round.
After absorbing a straight left and right hook from Muzuno, Kharitonov tagged his opponent with a straight right. With the Japanese fighter staggered against the ropes, Kharitonov delivered a massive knee to the face that sent Mizuno crashing to the canvas. Kharitonov scored two more punches on the floor, but they were hardly necessary.
The end came just 85 seconds into the opening round.
Kharitonov (17-4) picks up a win in his first MMA contest since April 2009 and is not 4-1 in his past five outings. Mizuno (8-7) has now lost two straight fights.
