Brian Nielsen (born April 1, 1965)in Korsør, Denmark. He is a Danish boxer who won the bronze medal in the 1992 Olympics in Barcelona and turned professional shortly after. Brian quickly earned a reputation of a man who could take a punch and didn't mind trading them with his opponents. Brian earned a nickname of 'Super', probably referring to the amateur days, where he fought super heavy weight. Brian always enters the ring to the voice of Eric Idle and the Monty Pythons, singing 'always look on the bright side of life'. Brian Nielsen went to equal the legendary Rocky Marciano's record of 49-0 before losing his 50th bout against Dick Ryan in an absurd match where Brian suffered from dehydration and was stopped by the referee without being hit by his opponent.However, since Nielsen was not a world Heavyweight champion, that is not considered a record. Later on in a rematch, Nielsen defeated Ryan.

Brian's only other loss was against Mike Tyson, in which he lasted six full rounds, before deciding to quit before the beginning of the seventh.

Nielsen also beat Larry Holmes.
