Michael Carbajal vs. Humberto González, billed as La Explosion, was a professional boxing match contested on March 13, 1993 at the Las Vegas Hilton for the IBF and WBC junior flyweight world championships.

In what could perhaps be called a rare case of boxing unity, both the WBC and IBF agreed to have their champions fight a unification bout.

The fight received much media attention both in the United States and in Latin America, with Carbajal and Gonzalez being featured on the cover of multiple magazines on the months preceding the bout.

Arum proved half prophetic in his guess that Carbajal would be the first junior flyweight to earn one million dollars in a fight: Both Carbajal and Gonzalez got a guarantee of one million dollars, after they paid their due fees, and Carbajal-Gonzalez I became the first time in history that a fight fought at the Flyweight division or a smaller one garnered one boxer that amount of money.

It was also the first time that a junior flyweight world title bout was shown as the main event of a Pay Per View fight card.

In the chief support, 1992 Olympics gold medallist Oscar De La Hoya faced Jeff Mayweather.

Gonzalez proved very slick for Carbajal, who had trouble finding his rival, but nonetheless, fought back furiously.

Michael Carbajal defended the IBF and WBC world junior flyweight titles twice before his second fight with Gonzalez.

Michael Carbajal and Humberto González were both elected as members of the International Boxing Hall of Fame in 2006.
