Julio César González Ibarra (July 30, 1976 – March 10, 2012) was a Mexican professional boxer who competed from 1997 to 2011, and held the WBO and lineal light heavyweight titles from 2003 to 2004.
Gonzalez followed that victory up with five more wins, including a 12-round unanimous decision over Julian Letterlough on February 2, 2001, that won him the regional NABO light heavyweight title - and propelled him into the No.
As the top contender, he earned a fight with WBC, WBA (Super), & IBF champion Roy Jones Jr. in July 2001, in Los Angeles.
Gonzalez earned his second shot at a world title on October 18, 2003, when he flew to Hamburg, Germany for a showdown with undefeated Dariusz Michalczewski for the Lineal & WBO light heavyweight championship.
