The fighters on the UFC Fight Night 121 card in Sydney on Saturday night put the judges to work. All six fights on the main card went the distance, including former heavyweight champion Fabricio Werdum’s unanimous decision victory over rising contender Marcin Tybura in the main event. It was the longest event in terms of fight time in UFC history. Werdum won for the second time in just more than a month. He accepted the fight after a 65-second victory over Walt Harris at UFC 216 in Las Vegas last month. Werdum hopes his third win in four fights since losing the belt to Stipe Miocic in May 2016 will earn him a championship rematch. “Congratulations to Marcin Tybura, he’s a great fighter and will have a long career,” the 40-year-old Brazilian said. “I’m a bit older but I want another belt before I go. I’ve got two championships on my wall and I want one more.” The three fights that preceded the main event all resulted in split decisions. Las Vegan Jessica-Rose Clark made a successful UFC debut by earning the nod over fellow Australia native Bec Rawlings in the fledgling flyweight division. “I knew that I would win this fight but it still feels amazing to get my first UFC win,” Clark said. “I can’t wait to get back in the gym and see what’s next.

Welterweights Belal Muhammad and Jake Matthews also earned split-decision wins. “This was the biggest win of my UFC career thus far,” Muhammad said after beating Tim Means. “It ended up being more of a brawl when it was supposed to be a wrestling match but I had fun out there. His range is a problem so I had to just bite down and go forward.” Muhammad called out controversial rising star Colby Covington for his next fight. Matthews won in his debut at 170 pounds after losing his last two bouts at lightweight as he edged Bojan Velickovic. “This was a very emotional fight for me,” the 23-year-old Australian said after the victory. “With my last two performances, I was very nervous
