Julio César Chávez vs. Greg Haugen was a professional boxing match contested on February 20, 1993, for the WBC super lightweight title.

A Chávez–Haugen super lightweight title fight was originally announced in October 1992 to take place on December 5 that same year at Caesars Palace in the Las Vegas Valley.

Organized by promoter Don King, the Showtime pay-per-view event was also set to include a WBC super welterweight title fight between Terry Norris and Simon Brown and a WBA super middleweight title rematch between Michael Nunn and Víctor Córdoba.

[3] On December 1, 1992, King announced a new event billed as The Grand Slam of Boxing scheduled to take place on February 20, 1993, in Estadio Azteca in Chávez's native Mexico.

[4][5] Leading up to the event, Haugen, a 25–1 underdog, engaged in frequent trash talk, insulting both Chávez and his home country of Mexico.

Nunn had made his first defence only three weeks earlier, scoring a wide unanimous decision in his rematch with former champion Víctor Córdoba on January 30.

Norris continued to dominate early in the 2nd, landing a hard left hand that sent Blocker against the ropes prompting referee Richard Steele to wave the fight off.

"[14] Chávez got off to a quick start, sending Haugen down to the canvas 25 seconds into the first round, and then proceeded to dominate the remainder of the fight.

With Haugen nearly defenseless, Cortez stepped in and ended the fight at 2:02 of the round, giving Chávez the victory by technical knockout.
