Joseph Benavidez, Henry Cejudo to coach on The Ultimate Fighter 24, fight in December

It's going to be an all-flyweight version of The Ultimate Fighter.

Joseph Benavidez and Henry Cejudo will coach against one another on the 24^th season of the show, which begins filming this summer and will air in the fall on FOX Sports 1, it was announced Wednesday on UFC Tonight. Then, the two flyweight contenders will meet in December in the co-main event of The Ultimate Fighter 24 Finale in Las Vegas.

Benavidez and Cejudo will coach teams of 125-pounders, who will battle it out in a 16-man tournament. The winner of the tournament will then face UFC flyweight champion Demetrious Johnson in the main event of the TUF 24 Finale.

The competitors on TUF will come from other organizations outside of the UFC, though there won't be a tryout for 125-pound fighters as originally planned, sources told MMA Fighting's Ariel Helwani.

Cejudo (10-1) is coming off a first-round TKO loss to Johnson at UFC 197 last month. He came into that undefeated. Cejudo, 29, is a former Olympic wrestling gold medalist.

Benavidez (24-4) has lost twice to Johnson in the past, but has won five straight, most recently a unanimous decision victory over Zach Makovsky in February. Benavidez, 31, has essentially defeated every other flyweight contender in the UFC except for Cejudo.
