Professional boxing is an extremely popular sport but the rise of MMA, a lack of a central governing body, corruption and players themselves have threatened to end this glorious sport. Mega fights still bring in huge revenues but they are few and far between, while numerous incidents contribute to the downfall. Here are some of them and a series of the worst fight videos ever:

Everybody is aware of corrupted Olympic judges and numerous stories about their unfair decisions. New Zealander Keith Walker was officiating a bantamweight bout between Byun Jong Il of South Korea and Alexander Hristov of Bulgaria.  The fight was an ugly foul-filled affair and Walker had to repeatedly penalize Jong for head butting. Finally Hristov was announced a winner, which incensed Jong’s countrymen. South Korean boxing officials and coaches stormed the ring and viciously attacked referee Keith Walker. The Korean Boxing Federation president and the president of the Korean Olympic Committee both resigned after this deplorable incident.

In 1996 Andrew Golota fought against Riddick Bowe. In the 7th round the fight began to take a very strange turn. For some reason Golota started to punch the rival below the belt line. He was warned several times and even received point deductions but his behavior continued unless the player was disqualified. That led to a riot where dozens of fans, boxing personnel and police were injured.

A superstar in South Korea, Kim earned a world title shot against the famed Ray “Boom Boom” Mancini in 1982. For Kim the fight was extremely brutal. In the 14th round Kim was knocked out, in spite of the fact that he managed to rise the referee stopped the fight. Minutes later Duk Koo Kim collapsed into a coma and was carried out of the ring and taken directly to the hospital.  Tragically the Korean star died 4 days later from severe brain trauma.  His mother committed suicide three months later, Ray Mancini reported that he blamed himself for Kim’s death.
