The main card for World Series of Fighting 17 is complete, as four bouts have officially joined Jake Shields vs. Brian Foster.

Set for January 17 from Planet Hollywood in Las Vegas, the main card airs on NBC Sports Network beginning at 9 p.m. ET.

Along with Shields-Foster, Brian Cobb meets Johnny Nunez, Krasimir Mladenov faces Brendan Kornberger, Bryson Hansen battles Rudy Morales and Adam Cella squares off with Danny Davis, Jr.

Cobb returns for his third appearance under the WSOF banner. In the promotion’s inaugural event, he earned a split decision win over Brazilian standout Ronys Torres. Nunez is an Xtreme Couture-trained athlete who has competed professionally since 2012 and boasts a perfect record through his first five starts. In March, Nunez made his first appearance for WSOF, earning a hard-fought split-decision victory over fellow top prospect Ozzy Dugulubgov.

The 28-year-old Mladenov is one of Bulgaria’s top fighting exports. Unbeaten through the first 11 fights of his career, Mladenov now fights for the third time under the WSOF banner after earning previous wins over the hard-hitting Angel DeAnda and Kendrick Miree. The hard-punching Kornberger has only been taken the distance once.

Xtreme Couture prospect Hansen looks to rebound from a disappointing August decision loss to Matt Sayles at WSOF 12. The loss came on the heels of a stellar 46-second KO of Sean Cantor. Morales, a Wand Fight Team prospect, will enjoy the opportunity to fight in his hometown of Las Vegas. After falling short in his pro debut, Morales has since earned three straight wins and now makes his WSOF debut.

Cella started his career 4-0 with four first-round stoppages and earned his way on to The Ultimate Fighter 17, though he came up short against eventual finalist Uriah Hall. Davis is on a four-fight winning streak that includes WSOF wins over Jorge Lopez and Phil Dace.
