WBC Orders William Zepeda vs Jadier Herrera for Lightweight Unification
The WBC has given champion Zepeda (34-1, 27 KO) and interim titleholder Herrera (18-0, 16 KO) until October 20th to cut a deal.

The WBC has ordered William Zepeda to defend his lightweight title against interim champion Jadier Herrera, and Frank Warren confirmed the two camps have until October 20th to agree terms. Zepeda, 34-1 with 27 knockouts, consolidated his claim in August by outpointing Lamont Roach Jr. at the Theater at Virgin Hotels in Las Vegas.
Herrera earned his seat at the table the hard way. The 24-year-old Colombian is 18-0 with 16 stoppages, a 89% finish rate, and he claimed interim gold by battering veteran Ricardo Nunez into submission after getting the green light while Shakur Stevenson moved up to chase Teofimo Lopez at 140.
How We Got Here
The sanctioning body's path to this point was messier than it needed to be. Stevenson was stripped over unpaid sanctioning fees — a legitimate reason — but instead of simply upgrading Herrera or booking a vacant-title fight, the WBC let Zepeda win the real belt against Roach, then ordered the mandatory anyway. Roach, incidentally, campaigns at super featherweight and sits #4 there with a 25-1-3 record, so the Zepeda fight was a step up in weight for him.
On paper, this is a tough night for Herrera. His standout win came against a hand-picked opponent fresh off a DQ loss to Jon Fernandez, and now he's being asked to solve one of the division's heaviest punchers. Zepeda is a long, high-volume problem for anyone at 135 in the post-Stevenson landscape.
The Escape Hatches
There are a couple of ways this doesn't happen. Zepeda could pursue a full unification with WBO champion Abdullah Mason, who is 21-0 with 18 knockouts and coming off a 12th-round stoppage of Albert Bell. Or he could follow the current fashion and simply vacate rather than fight a mandatory.
Barring either of those, Herrera gets his shot. Warren wants the fight, Herrera wants the fight, and the WBC has put a date on the clock. If both sides play ball by the 20th, the division gets a clean answer about whether the 24-year-old is the real deal or just the beneficiary of some creative sanctioning math.
