A BOXING referee showed off his world-class granite chin after Mexican star Mario Aguilar caught him flush with a left hook.<br /><br />Aguilar was in action against unbeaten cruiserweight prospect Brandon Glanton with the vacant WBO world title on the line.<br /><br />Going into the contest as a massive underdog, the 31-year-old was looking to drop big bombs in pursuit of him to cause an upset.<br /><br />And he hit a perfect shot that he would have been dreaming of...only it connected with the referee.<br /><br />But in unbelievable scenes, the official simply shrugged it off after initially stumbling backwards in a video shared by Twitter user @GloversStories.<br /><br />He then resumed his duties where he then separated Aguilar and Glanton after the latter was put in a headlock.<br /><br />The fight didn't last long after that, as Glanton racked up his 17th straight victory after knocking his opponent out with a left hook to the body in the second round.<br /><br />But it was the referee's iron jaw that turned out to be the talking point, as @GloversStories put it: "THE REFEREE HAS A CHIN."<br /><br />In response to the video, boxing promoter Loui DiBella tweeted: "This really happened tonight. The best punch of the round lands flush with the referee."<br /><br />Another commented: "He took it well."<br /><br />This boxing supporter later joked, "[Amir] Khan would have been doing the chicken dance after that landed."<br /><br />Meanwhile, one joked: "What the clip doesn't show is the referee coming back with a steel chair."<br /><br />It's not uncommon for referees to be accidentally punched inside the ring, with a female official showing just how tough she was after being punched during a heavyweight competition at the Commonwealth Games.<br /><br />Although Mexican referee Jesús Granados had to leave the ring on a stretcher in April after Irvin Turrubiartes punched him.
