Boxing has a long and storied history filled with memorable moments that have captivated audiences around the world. However, alongside the triumphs and displays of skill, the sport has also seen its fair share of controversies. From disputed decisions to shocking incidents, these moments have sparked debate and left a lasting impact on the sport. Here are five of the most controversial moments in boxing history:

The Bite Fight (1997): In a highly anticipated rematch between Evander Holyfield and Mike Tyson, Tyson stunned the world by biting off a piece of Holyfield's ear during the third round. The fight was immediately stopped, and Tyson was disqualified, leading to widespread condemnation and a lengthy suspension for Tyson.

The Phantom Punch (1965): In a bout between Muhammad Ali (then known as Cassius Clay) and Sonny Liston, Ali delivered a quick right hand that dropped Liston to the canvas. However, many observers believed Liston took a dive, leading to allegations of a fixed fight.

The Olympic Robbery (1988): In the final of the light welterweight division at the Seoul Olympics, South Korean boxer Park Si-hun was awarded a controversial victory over American Roy Jones Jr. Despite dominating the fight, Jones was denied the gold medal in a decision that was widely criticized as a hometown favoritism.

The 'No Mas' Fight (1980): In a highly anticipated rematch between Sugar Ray Leonard and Roberto Duran, Duran shocked the boxing world by uttering the words "No mas" (Spanish for "no more") in the eighth round, signaling his surrender. The exact reason for Duran's capitulation remains a subject of debate to this day.

The Tyson vs. Douglas Upset (1990): In one of the biggest upsets in boxing history, Mike Tyson, considered unbeatable at the time, was knocked out by Buster Douglas in the tenth round. The result stunned the boxing world and led to questions about Tyson's preparation and mindset.
