The UFC confirmed three planned title fights for June and July, including Jon Jones defending his belt.
Jones, who hinted that he might try his hand at heavyweight vs. Stipe Miocic, will instead defend his 205-pound title for a second time this year as he takes on Thiago “Marrieta” Santos.
The Jones-Santos bout headlines UFC 239 on July 6 from the T-Mobile Arena in Las Vegas.
Also on the card will be Amanda Nunes putting her bantamweight belt on the line vs. former champion Holly Holmes. Nunes claimed the featherweight belt last year with a knockout win over Cris Cyborg.
At UFC 238 will be flyweight champion Henry Cejudo battling Marlon Moraes for the vacant bantamweight belt.
For the vacant bantamweight belt!

Cejudo knocked out TJ Dillshaw earlier this year to defend his title, with Dillashaw being stripped of the bantamweight championship after failing a drug test. Moraes is a former World Series of Fighting champion.
The Jones-Santos, Nunes-Holm matches were first reported by ESPN.
