Brian Nielsen

Nielsen met Holyfield on May 7, 2011 in a World Boxing Federation (WBF) title bout, in Copenhagen. Holyfield won the fight, knocking Nielsen down in the 3rd with a left hook and stopping him by TKO in the 10th.

On February 8, 2010, Brian Nielsen told reporters that he was prepared to return to the ring, after 8 years of absence, and that a proposed fight against Evander Holyfield had been met with interest by both sides. Though originally thought unrealistic by former promoter Mogens Palle, due to Nielsen's bad knee, Nielsen's comeback was confirmed by Nielsen's promoter Sauerland Event on June 1, 2010.

Controversy arose in early 2004, when journeyman heavyweight Thomas Williams stated that he had been bribed to throw his fight against Nielsen in March, 2000. Along with promoter Robert Mitchell, Williams was indicted by the United States District Court for the District of Nevada for match fixing in order to promote the career of Richie Melito, and it was during the FBI's investigation of that case that Williams admitted to intentionally losing to Nielsen. The fix was arranged by promoter Robert Mittleman, a frequent associate of Nielsen's promoter Mogens Palle, who later confessed that he had been paid $1,000, while Williams had received "up to $40,000" from Palle in order to lose the fight. Williams, Mitchell and Mittleman were all found guilty of sports bribery by the court in November and December, 2004.

On 13 October 2001, Nielsen fought Mike Tyson at the Parken Stadium in Denmark. After six rounds heavily in Tyson's favour, Nielsen quit on his stool citing an eye injury. Nielsen was knocked down once in the third round.

After his win over 41-year-old ex-World Boxing Association champion James 'Bonecrusher' Smith in October 1994, Nielsen began to attract attention. He went on to hold the minor IBO belt during an unbeaten streak equaling that of legend Rocky Marciano. He later held the minor IBC belt.

As an amateur, Nielsen won bronze medals in the super heavyweight division at the 1991 European Championships and the 1992 Olympics in Barcelona.

In total, Nielsen boxed 111 fights as an amateur and won 104. He only took a count once in amateur career, and only once was he stopped before time - during the 1989 European Championship bout, where he suffered a cut near one of his eyes. His opponent at this match was the Greek boxer George Tsachakis who attended the final.

He was both Zealand champion and Danish champion for five consecutive years (1988-1992), and also won numerous international tournaments. His career as an amateur ended after the Olympics in Barcelona in 1992 where he won the bronze. In the semifinals he lost to the powerful Cuban Roberto Balado. Balado won 15 to 1.

Brian Nielsen (born 1 April 1965) is a Danish former professional boxer. He held the IBO heavyweight title from 1996 to 1999 successfully defending it five times, including against a 48 year old Larry Holmes and Phil Jackson, the second highest number of defenses behind Wladimir Klitschko's record of 18. At one point of time, he equaled Rocky Marciano's record of 49 successive wins with no losses. While he never held a world title from any of the main four sanctioning bodies (WBC, IBF, WBA, WBO), he did defeat several former world champions who had, including Orlin Norris, Carlos De León, Jeff Lampkin, and Tony Tubbs.

The Nielsen vs. Williams fight was the 57th of Nielsen's career. Nielsen and Mogens Palle denied any knowledge of the match fixing, and were not charged of any wrongdoing by American or Danish authorities.
