With the UFC heading to Brazil on Aug. 1 with women’s bantamweight champion Ronda Rousey (11-0) vs. undefeated contender Bethe Correia (9-0), officials from fellow Las Vegas-based MMA promotion WSOF have elected to go head-to-head with their most auspicious card to date.

WSOF President Ray Sefo told USA TODAY Sports and MMAjunkie that WSOF 22, which takes place at Planet Hollywood Resort & Casino in Las Vegas, will feature three championship fights, as well as the return of former kickboxing world titleholder Tyrone Spong.

As with all WSOF events, the four-fight main card airs on NBCSN (11 p.m. ET) following prelims on MMAjunkie.

In addition to a previously reported headliner of WSOF welterweight champ Rousimar Palhares (17-6), who’s an honorable mention in the USA TODAY Sports/MMAjunkie MMA welterweight rankings, vs. No. 9-ranked Jake Shields (31-7-1), WSOF 22 also includes bantamweight champ and No. 9-ranked Marlon Moraes (14-4-1) vs. Sheymon Moraes undefeated (7-0).

Additionally, Spong (2-0) takes on Strikeforce vet Mike Kyle (21-12-1), and the company will introduce its flyweight title with Magomed Bibulatov (9-0) vs. Donavon Frelow (4-0) for the inaugural belt.

“This is, in my opinion, the most incredible lineup of fights featuring marquee talent that WSOF has put together since we launched the company in 2012,” Sefo said.

The latest WSOF 22 lineup now includes:
