Henry Cejudo declared himself the best combat sports athlete of all time and the former Olympic champion has a legitimate claim after adding a UFC bantamweight title to his flyweight crown. His Brazilian opponent, Marlon Moraes, came into the fight as the favourite and looked serene in the opening round, comprehensively out-striking his opponent. The former champion TJ Dillashaw gave up the belt having been found to have used a banned substance so Cejudo and Moraes locked horns for the vacant title in Chicago. Henry Cejudo claimed the bantamweight title to go with his flyweight crown and said he is the best to ever do it He beat Brazilian Marlon Moraes in the third round as referee Marc Goddard waved off the main event contest Cejudo pushed the pace and his opponent simply could not handle his output, suffering a number of telling blows And after five minutes it looked like Moraes was the man most likely to seize the crown. But Cejudo, who famously beat Demetrious 'Mighty Mouse' Johnson, showed championship class in making the necessary adjustments. His opponent was the bigger man and perhaps the weight cut played a part, slowing him down as the fight wore on. Cejudo put a stunning pace on the Brazilian and started becoming the aggressor early on in the second round. He found plenty of success with knees from the clinch, dazing Moraes to the head and punishing him to the body. In the third round, Moraes looked a spent force and it was a matter of time before he succumbed. Cejudo hauled his man to the canvas and landed brutal ground and pound. The referee Marc Goddard mercifully intervened and Cejudo was crowed two-weight world champion. Afterwards he declared: 'My name is CCC, Olympic champ, flyweight champ and bantamweight champ. I'm the best combat sports athlete of all time. Valentina Shevchenko retained her flyweight title against Jessica Eye with one of the most brutal knockouts in UFC history. Valentina Shevchenko (left) knocked out Jessica Eye with a brutal head kick in the co-main event of the evening The challenger was out cold for a long time but thankfully came around and was helped from the octagon Shevchenko retained her title and she will take some beating on the evidence of Saturday's performance The champion landed some scything kicks to the body in the first round and set her challenger up for a head kick in the second. She duly delivered and Eye was unconscious for a concerning length of time. Eventually she came around and asked whether she'd been knocked out. Perhaps she won't want to see the replay because it was a horrible blow to the head from Shevchenko's shin. The Kyrgyzstani–Peruvian athlete possesses such an arsenal of deadly strikes and looks almost unstoppable as the division's queen. From the first minute, Shevchenko was in total control and it was only the buzzer that prevented her from sinking in a submission in the opening stanza. The striking and grappling both looked incredibly sharp and the champion addressed the crowd in three different languages after her victory. An impressive night's work. Donald Cerrone's highly anticipated fight with Tony Ferguson ended in controversial and massively disappointing circumstances. 'Cowboy' was forced to stop fighting by medics after his eye totally closed up. Ferguson landed a late blow after the bell in the second round, prompting a chorus of boos in the arena. Cerrone was already cut up and was showing plenty of damage from a back-and-forth first ten minutes but made the mistake of blowing his nose, causing the eye to swell up, a mistake he later admitted was avoidable given his vast experience in the sport. The second round went Ferguson's way after a perfectly poised first. 'El Cucuy' was his typically active self and showcased some nasty elbows to go with the relentless engine. Understandably, the crowd were devastated at being robbed of a natural conclusion but the doctors had little choice but to wave it off given Cerrone's total inability to see out of his right eye. Ferguson accepted it was not the way he wanted to win and was gracious afterwards, saying he'd happily have a rematch. Petr Yan called for a bantamweight title fight after outpointing Jimmy Rivera with a clinical display. Rivera performed well throughout but the major moments belonged to his Russian opponent. The bantamweight produced two knockdowns at the end of the first two rounds to leave the judges in no doubt about who had gained superiority over five minutes. Rivera came back well in the third after his coaches told him to go for the knockout but ultimately couldn't produce the killer blow. He made use of a number of high quality and spiteful low kicks and perhaps should have persisted with them. Blagoy Ivanov opened up the main card with a hard earned victory against popular Australian Tai Tuivasa. The Bulgarian showed enormous bottle and one hell of a chin to stand and trade with his opponent as they put on a brilliant heavyweight show for the Windy City crowd. Blagov dropped Tuivasa in the first and was rewarded for his display with a unanimous decision. Tuivasa looked particularly dangerous coming out of the clinch but appeared to land fewer clean, thudding shots. All rights reserved for this news site dailymail and under his responsibility
