How to watch 'The Ultimate Fighter' -- Conor McGregor vs. Michael Chandler

"The Ultimate Fighter," the reality show that brought fighters together in a home, is on ESPN and ESPN+.

The reality series launched the mixed martial arts explosion around the world in 2005. Over the course of 12 weeks, 16 up-and-coming mixed martial artists fought to stay in the house while receiving world-class coaching from the UFC's elite fighters. The winner was declared the Ultimate Fighter and earned a six-figure UFC contract.

The iconic reality series has launched the careers of numerous fighters who went on to become UFC champions, contenders and stars, including Kamaru Usman, Tony Ferguson, TJ Dillashaw, Rose Namajunas, Michael Bisping, Nate Diaz, Michael Chiesa, Al Iaquinta, Kelvin Gastelum, Forrest Griffin, Rashad Evans and Uriah Hall. Among the many greats to coach on the show is Conor McGregor, who led a team on TUF 22 in 2015.

And on Feb. 4, 2023, Dana White announced that McGregor will coach Season 31 against Michael Chandler. The two will fight later in 2023. This season will be broadcast on ESPN and ESPN+, beginning on May 30.
