Berchelt (37-1, 33 KO's) vs. Valdez (28-0, 22 KO's) was a mandatory fight under the World Boxing Council.
Berchelt has already had six successful defenses of the 130-pound championship of the body, five of them won by knockout. Valdez would be in search of his second division world title belt after having held the featherweight world title under the World Boxing Organization (WBO).
