However much longer Emanuel Navarrete has left at super bantamweight, it will last at least through Saturday evening.

The streaking 122-pound titlist from Mexico City, Mexico and unbeaten but unheralded title challenger Francisco de Vaca both made weight ahead of their ESPN-televised main event Saturday evening at Banc of California Stadium on USC campus in Los Angeles, Calif.

Both fighters came in right at the 122-pound limit for their headliner, with the show airing live beginning at 10:00pm ET/7:00pm PT.

Navarrete (27-1, 23KOs) attempts the second defense of the 122-pound title he claimed just eight months ago. His title win and first defense both came versus Isaac Dogboe, dethroning the previously unbeaten titlist in a 12-round decision last December which he followed with a one-sided 12th round stoppage this past May.

Both bouts aired live on ESPN, with Saturday's headliner marking his third straight network appearance.

Phoenix (Az.)-based de Vaca (20-0, 6KOs) takes his first swing at a major title, along with his televised debut.

In the evening's chief support, former 122-pound titlist Jessie Magdaleno and veteran contender Rafael Rivera collide in a 10-round featherweight crossroads clash.

Las Vegas-based Magdaeleno (26-1, 18KOs) weighed 125.4 pounds for his second fight since losing his title to Dogboe last April; Mexico's Rivera (27-3-2, 18KOs) tipped the scales at 125.6 pounds in search of his second win following a failed title bid versus featherweight titlist Leo Santa Cruz earlier this year.

Also on the card, South Africa's Chris Van Heerden fights for the second time under the Top Rank banner as he takes on Aslanbek Kozaev in a 10-round welterweight bout.

van Heerden (27-2-1, 12KOS) weighed in at 146.5 pounds, while Russia's Kozaev (32-3-1, 8KOs) came in right at the 147-pound limit.
