Set for June 9 from Chicago and the United Center, the event also features Rafael dos Anjos and Colby Covington meeting for the interim belt.

Whittaker (20-4) claimed the interim title last year when he defeated Romero (13-2). He was later unified as champion when Georges St-Pierre vacated the belt. Romero defeated Luke Rockhold recently to secure his shot at the champion.

Undefeated at 185 pounds, Whittaker has earned spectacular wins against Ronaldo “Jacare” Souza, Derek Brunson, Uriah Hall and Brad Tavares. Along with his performance vs. Rockhold, Romero – a former Olympic silver medalist – has also topped the likes of Chris Weidman, Lyoto Machida and Brunson.

Dos Anjos and Covington will meet to crown the interim titleholder, with the winner setting themselves up for a battle with champion Tyron Woodley later this year. The two have been on a collision course for quite some time, with Covington making disparaging remarks about Brazil that angered RDA.

The card also features Alistair Overeem vs. Curtis Blaydes, Andrei Arlovski vs. Tai Tuivasa, Rashad Evans vs. Anthony Smith, Joseph Benavidez vs. Sergio Pettis and Claudia Gadelha vs. Carla Esparza. Overeem, Arlovski, Evans, Benavidez, Gadelha and Esparza are all either former UFC champions or challengers to the title in their respective weight divisions.

Tickets for UFC 225 go on sale to the general public this Friday at 11 a.m. ET and are priced between $63-$303, with a limit of eight per person through Ticketmaster.
