On December 5, 1986, Haugen captured the IBF lightweight title with a majority decision over reigning champion Jimmy Paul.[3] On February 23, 1991, he captured the WBO light welterweight title with an upset victory over then undefeated Hector Camacho by split decision, an outcome that resulted from Camacho being deducted a point for illegally hitting Haugen when Haugen refused to touch gloves at the beginning of the last round.On February 20, 1993, he challenged Mexican legend Julio César Chávez for the WBC light welterweight title at Azteca Stadium in Mexico City, a fight attended by 132,247 spectators.Leading up to the bout, Haugen made the comment that many of Chavez's wins "came against Tijuana taxi drivers that my mom could whip.Within seconds of the opening round, Chavez dropped Haugen with a straight right hand, but rather than dispatching him quickly, pulled back with the intent of punishing him for his pre-fight remarks.
