The UFC flyweight championship will be on the line this Saturday night, as John Dodson challenges Demetrious Johnson at UFC 191.

Set for Las Vegas and the MGM Grand Garden Arena, the main card airs live on pay-per-view after prelims on FOX Sports 1 and UFC Fight Pass.

This marks the second meeting between Johnson and Dodson, as “Mighty Mouse” was pushed to the distance by the former Ultimate Fighter winner the first time around.

Along with that contest, former UFC heavyweight champions Frank Mir and Andrei Arlovski collide in the co-main event. Mir and Arlovski both find themselves in a career resurgence as of late, and the winner will be able to move one step closer to competing for the belt once more.

Also, two light heavyweight matches are scheduled, as former title contender Anthony Johnson meets Jimi Manuwa and Corey Anderson battles Jan Blachowicz.

Female strawweight prospect Paige VanZant returns, taking on Alex Chambers to start the main card.

Ross Pearson-Paul Felder highlight the prelim lineup, along with Francisco Rivera-John Lineker, Jessica Andrade-Raquel Pennington and Tiago Trator-Clay Collard.

Joe Riggs vs. Ron Stallings and Joaquim Silva vs. Nazareno Malegarie air on Fight Pass beginning at 7 p.m. ET.

FightLine will have you covered all week with the latest news, along with weigh-ins and fight night coverage of the event.
