“The Big Ticket” sent the “The Boa Constrictor” crashing on the mat as he channeled his inner Jorge Masvidal to knock him out in just 12 secs of the first round. Known for his vicious ground game, Oleinik’s game plan was to take Harris to the ground and keep him there. But the lightning fast heavyweight made sure he didn’t needed to use any of his ground skills. Instead he went for a jumping knee followed by a straight left that landed on the jaw. Oleinik’s ankle gave up on him during this exchange and he dropped instantly covering up. Harris’s 12-second finish is now the third-fastest knockout in UFC heavyweight history.
