UFC president Dana White confirmed the fight shortly after midnight on ESPN.

This is the third title fight set for UFC 205, joining women’s strawweight champion Joanna Jedrzejczyk vs. Karolina Kowkiewicz and welterweight champion Tyron Woodley vs. Stephen Thompson.

McGregor will remain the featherweight champion through UFC 205, giving the Irishman a chance to become the first UFC fighter to hold titles in multiple weight classes at the same time. He also is trying to become the third fighter to win a UFC title in more than one weight class (Randy Couture and BJ Penn are the others).
