Nathaniel "Nate" Campbell III (born March 7, 1972) is an American former professional boxer who competed from 2000 to 2014, and currently works as a TV host. In boxing he held the unified WBA (Undisputed), IBF and WBO lightweight titles from 2008 to 2009, as well as having challenged for the IBF super featherweight title in 2005 and the WBO junior welterweight title in 2009. Professional career Early years at lightweight Campbell turned professional in 2000 in Tallahassee and quickly stormed through his opponents. He won his first 23 fights, setting up a bout with cagey veteran Joel Casamayor in 2003. Super featherweight Casamayor won a unanimous decision, but many commentators, including those for HBO, believed that Campbell had fought a much closer match then what the scorecards indicated. Some commentators even stated that Campbell had won that closely fought match. After that bout Campbell slipped into obscurity after two defeats to Robbie Peden and a loss to Francisco Lorenzo. In the first loss to Peden, Campbell appeared to drop his hands to taunt his opponent and was promptly knocked out. After these fights, many in the boxing world believed that Nate Campbell's boxing days were over. Return to lightweight Nonetheless, Campbell stormed back on the scene in 2005 with a big win over undefeated prospect Almazbek "Kid Diamond" Raiymkulov. In 2006 he lost a split decision to Isaac Hlatshwayo, but won an IBF title eliminator against Matt Zegan. Instead of a title shot, Campbell's next bout was another eliminator, which he won over Ricky Quiles. After knocking out Wilson Alcorro, his next bout was a split decision victory over the undefeated Juan Díaz on March 8, 2008 to become the new IBF, WBA, and WBO unified World Lightweight Champion. Campbell was the underdog coming into the fight, as Díaz was considered too strong and too technically sound. But Campbell surprised the boxing world by controlling the tempo of the fight. The first 7 rounds were heavily contested but from the 8th round afterwards, Campbell completely controlled the fight as Diaz's eyes began swelling. Campbell's first defense of his recently won WBA, WBO and IBF titles was to be against Joan Guzmán who just moved up from the Super Featherweight division. The fight was to take place at the Beau Rivage Resort & Casino, Mississippi, United States on September 13, 2008. But because Guzman weighed in more than 3 pounds
