The Ultimate Fighting Championship returns after its first pay-per-view event of the year with an ESPN+ card featuring a heavyweight bout between former champion Junior dos Santos and Curtis Blaydes. The card is now official as every fighter has successfully made weight prior to Saturday's event in Raleigh, North Carolina.
Dos Santos (21-6) will be looking to rebound from a quick knockout loss at the hands of Francis Ngannou. The 35-year-old had been on a three-bout win streak before that having picked up victories over Derrick Lewis, Tai Tuivasa and Blagoy Ivanov. "Cigano" has no trouble making the heavyweight limit and came in at 247 pounds.
Blaydes (12-2, 1 NC) will have a chance to notch the biggest victory in his career against dos Santos. He was also stopped by Ngannou in his last defeat but has bounced back with dominant wins over Justin Willis and Shamil Abdurakhimov. Surprising no one, Blaydes made weight and came in at 248 pounds.
The co-main event is an intriguing welterweight match as former lightweight champ Rafael dos Anjos will face off against Michael Chiesa. Dos Anjos (30-12) is 1-3 in his last four fights but his losses have come to a murderer's row of Leon Edwards, Kamaru Usman and Colby Covington. The Brazilian will look to show that he has more left in the tank against Chiesa (16-5), who has looked great since moving up 170 pounds as he dominated Carlos Condit and Diego Sanchez.
UFC Fight Night 166's entire card will air on ESPN+ starting at 5 p.m. ET/2 p.m. PT.
