Zuffa Boxing 08: De Los Santos vs. Valenzuela II Headlines Las Vegas Rematch Night

Zuffa Boxing 08 takes place on Sunday, 28th June 2026, at The Chelsea at The Cosmopolitan of Las Vegas, with Edwin “La Granada” De Los Santos meeting Jose “Rayo” Valenzuela in a 10-round lightweight rematch. The event is one of the more compelling early cards under the Zuffa Boxing banner because it pairs a violent history with real stakes for both fighters.

Main Event

Edwin De Los Santos enters the rematch with the confidence of having won the first meeting in dramatic fashion. Back in September 2022, he stepped in on short notice, survived an early knockdown, and stopped Valenzuela by third-round knockout in a fight that made a strong impression.

Jose Valenzuela gets the chance to rewrite that story in Las Vegas. He is 15-3 and clearly motivated to avenge the first professional loss of his career, especially now that both men are signed to the TKO-backed Zuffa Boxing project.

That makes the main event more than just a rematch. It is a chance for one fighter to confirm supremacy and for the other to erase the memory of a painful defeat.

Co-Main Event

The co-main event features undefeated Mexican prospect Omar Trinidad against former world champion Jerwin Ancajas at featherweight. Trinidad comes in at 20-0-2 and has the kind of unbeaten record that gives a fight instant momentum.

Ancajas brings a very different kind of value. At 38-4-2, he is the more experienced name and is making his debut in the division, which adds a layer of uncertainty to an already interesting matchup.

Main Card Opener

Cain Sandoval vs. Brandun Lee opens the main card in junior welterweight action. Sandoval is trying to rebound and strengthen his standing, while Lee brings a perfect 30-0 record and major power with 23 knockouts.

That is the sort of fight that can set the tone for the whole night. If Lee looks sharp, he reinforces his reputation as a dangerous unbeaten contender; if Sandoval wins, he turns the opener into a major statement.

Preliminary Spotlight

The featured preliminary bout puts unbeaten Las Vegas native Floyd Diaz against Mexico’s Andres Teran in a bantamweight showcase. Diaz is 14-0 with three knockouts, and this is a valuable second appearance for him under the new promotion.

Teran arrives with a 18-2 record and 13 knockouts, so the matchup has real danger. A prospect fight like this often ends up being one of the most telling bouts on the undercard.

Final Outlook

Zuffa Boxing 08 has a strong foundation because the main event already carries built-in drama from the first fight. De Los Santos vs. Valenzuela II gives the card a genuine rivalry feel, while the co-main and opener provide depth across the lineup.

If the rematch lives up to the original, Las Vegas could get one of the more memorable early Zuffa Boxing shows.
