Michael Carbajal vs. Humberto González I was a professional boxing match contested on March 13, 1993 at the Las Vegas Hilton for the IBF and WBC junior flyweight world championships. The fight made boxing history in many ways. While this pair of world champions fought three times, their first fight is the one that writers and fans usually remember with fondness. Background In boxing, there are certain types of "rivalries" that fans get excited about most of the time. When a Puerto Rican fighter faces a Mexican, for example, in a major title fight, most of the time the fight itself is considered a big boxing event.

Knowing that this was a well talked about match-up, promoter Arum began to work towards making it happen. 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 date set was March 13, 1993.
