A former world champion claims that Lennox Lewis once admitted he should have retired with three defeats on his professional record.<\/p>\n
\u2018The Lion\u2019 is considered one of the all-time greatest heavyweights, retiring in 2003 after having avenged his only two losses against Oliver McCall and Hasim Rahman.<\/p>\n
Lewis also enjoyed a successful rematch with Evander Holyfield, who had somehow retained his world titles with a controversial draw<\/a> in their first encounter.<\/p>\n Later that year in 1999, though, Lewis managed to become the undisputed heavyweight champion with a unanimous decision victory, maintaining his lineal status until ending his career with a sixth-round finish over Vitali Klitschko<\/a>.<\/p>\n It was back in 1996, however, that many felt the Brit should have suffered another defeat, this time against Ray Mercer, who had briefly held the WBO title in 1991.<\/p>\n The American ultimately vacated his belt and was defeated by Larry Holmes the following year, before losing a 10-round unanimous decision to Holyfield in 1995.<\/p>\n \u2018Merciless\u2019 then faced Lewis in a battle between two Olympic gold medallists, this time suffering a highly contentious 10-round majority decision defeat.<\/p>\n
