Edwin De los Santos vs Jose "Rayo" Valenzuela Headlines Zuffa 08 from the Chelsea at Cosmopolitan

Zuffa Boxing returns with a highly anticipated lightweight rematch between Edwin De Los Santos (17-2, 15 KOs) and Jose “Rayo” Valenzuela (15-3, 9 KOs) on Sunday, June 28, which headlines an eight-fight event from The Chelsea at The Cosmopolitan of Las Vegas. The three-fight main card will stream live at 9pm ET/6pm PT on Paramount+.

In the co-main event, Omar Trinidad (20-0-2, 14 KOs) of Los Angeles takes on former world titlist Jerwin Ancajas (38-4-2, 25 KOs) of the Philippines in a 10-round featherweight scrap. Following a dominating Zuffa Boxing debut against Max Ornelas, the 30-year-old Trinidad will face the most experienced opponent of his career in Ancajas, who reigned as super flyweight champion for more than five years.

Opening the main card on Paramount+, Sacramento’s “Sugar” Cain Sandoval (17-1, 15 KOs) will take on Southern California standout Brandun Lee (30-0, 23 KOs) in a 10-round fight. The 23-year-old Sandoval looks to bounce back following his first career loss against Julian Rodriguez earlier this year in the inaugural Zuffa Boxing event.
