The boxing world was left in shock as Nick Ball, the undefeated champion, suffered a brutal knockout defeat in the 12th and final round to Brandon Figueroa. This loss marked the first defeat of Ball's career, and it happened right in front of his home crowd in Liverpool. But here's where it gets controversial... The fight appeared to be heading for the scorecards until Figueroa, the 29-year-old American, produced a left-handed shot to drop the champion to the canvas in the 12th round. Although Ball managed to get back to his feet, Figueroa wasn't done yet. He put Ball between the ropes and the referee waved off the bout, ensuring the fight didn't go to the scorecards. This controversial ending sparked a melee between both camps, with celebrations from Figueroa's team spilling over into the ring. Ball, who had tried to force the pace, couldn't hold off Figueroa's relentless attacks. As the fight entered its closing three minutes, Figueroa sent Ball to the canvas with a strong left hand, and he didn't let up. Ball regained his feet, but Figueroa sensed his opportunity and completed the job soon after, dropping Ball onto the ropes. This win makes Figueroa a three-time world champion. But what's next for Figueroa? New champion Figueroa could now be set for a slot on the undercard of Canelo Alvarez's comeback fight in September. After losing to Terence Crawford in a defense of his undisputed super-middleweight championship, Alvarez is expected to return to boxing in Saudi Arabia later this year. Saudi financier Turki Alalshikh wants Figueroa to feature on the bill, and he posted on social media, "A huge congratulations to Brandon Figueroa for showing his character and traveling to the champion's backyard to capture the WBA featherweight championship with a great knockout in the final round. We want to see you defend your title for the first time on September 12 in Riyadh, when we stage 'Mexico vs the world' - featuring the return of Mexican superstar Saul 'Canelo' Alvarez in the main event." This controversial ending has left many questions unanswered, and it's sure to spark debate and discussion among boxing fans. What do you think? Do you agree with the referee's decision?
