UFC Fight Night results, highlights: Jairzinho Rozenstruik scores first-round knockout of Augusto Sakai

Very little happened for nearly the entirety of the opening round in Saturday's UFC Fight Night main event between Jairzinho Rozenstruik and Augusto Sakai. But heavyweights -- especially those with Rozenstruik's heavy hands -- only need one moment to change a fight. That's exactly what happened when Rozenstruik connected with a left hand that set up a finishing flurry with just one second left in the first round.
