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 and gym owner of Galaxxy Boxing Refuge.
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.
Nonetheless, Campbell stormed back on the scene in 2005 with a big win over undefeated prospect Almazbek "Kid Diamond" Raiymkulov.
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'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.
On January 10, 2009, Campbell vacated his WBA lightweight title because of concerns regarding sanctioning fees and proposed mandatory defenses.
[1] Just as Guzman had trouble making weight, Campbell experienced a similar problem as he was supposed to defend his IBF and WBO lightweight crowns against Ali Funeka on February 14, 2009.
The Jacksonville native moved up to the light welterweight division after he failed to make the lightweight limit in his last fight against Ali Funeka.
Campbell's lead trainer is former world champion John David Jackson, and his business advisor is One Punch Productions.
On November 27, 2010, Campbell lost an eight-round decision on the Juan Manuel Márquez undercard in Las Vegas to Walter Estrada, a journeyman whose record included only three wins over winless fighters in twelve bouts between 2008–2010.
