Demetrious Johnson didn’t want to wait around until the end of “The Ultimate Fighter 24” to defend his UFC flyweight title again. Now he won’t have to, because his next defense is set, and Wilson Reis is his challenger.

The flyweight title bout between Johnson (24-2-1 MMA, 13-1-1 UFC) and Reis (20-6 MMA, 4-2 UFC) will co-headline July’s UFC 201 lineup.

UFC officials today announced the bout during FOX Sports 1’s “UFC Tonight” broadcast.

UFC 201 takes place July 30 at Phillips Arena in Atlanta, Ga. The main card airs on pay-per-view following prelims on FOX Sports 1 and UFC Fight Pass, though the bout order hasn’t been finalized.

Johnson, No. 1 pound-for-pound and at flyweight in the latest USA TODAY Sports/MMAjunkie MMA rankings, has earned eight consecutive 125-pound title defenses as the one and only champion in divisional history. He must recently scored a first-round TKO of Olympic gold medalist Henry Cejudo at UFC 197 in a bout pegged as one of his toughest to date.

“Mighty Mouse” recently revealed he signed a new eight-fight UFC contract, and the bout with Reis will apparently be the first. If he gets past the Brazilian, Johnson, 29, will fight the winner of “TUF 24,” which will bring all the top flyweight talent outside of the UFC for a tournament to discover the next title challenger.

Reis will bring three victories in his past four fights into his first UFC title bout, the most recent of which saw him beat Dustin Ortiz by unanimous decision at UFC on FOX 18 in January. The No. 9-ranked flyweight has suffered just one blemish in the weight class, and that came against Jussier Formiga at UFC Fight Night 67 in May 2015.

The latest UFC 201 card now includes:

Champ Robbie Lawler vs. Tyron Woodley – for welterweight title

Champ Demetrious Johnson vs. Wilson Reis – for flyweight title

Siyar Bahadurzada vs. Claudio Silva

Damien Brown vs. Cesar Arzamendia
