Flyweight champion Demetrious Johnson will put his title on the line against his toughest competitor to date when John Dodson meets him in the main event of UFC 191 on Saturday night from Las Vegas.
Johnson and Dodson first met in 2013 with the champion beating the challenger by unanimous decision, but not before the former "Ultimate Fighter" winner giving him everything he could handle and more.
Dodson still stands as the only fighter at 125 pounds to drop Johnson with a punch, and he hopes to do the same and more when he meets him for the rematch at UFC 191.

Also on the card, legendary heavyweights and former UFC champions Andrei Arlovski and Frank Mir meet more than a decade after their first was scheduled but never came to fruition.
Back in 2004, Mir was the champion but suffered massive injuries in a horrific motorcycle accident that pushed him out of action for nearly two years while also cancelling his bout with interim titleholder Arlovski.
Now they will finally meet as both heavyweights are surging with five straight wins in the UFC between the two of them.
Strawweight star Paige VanZant is also back in action at UFC 191 when she takes on "Ultimate Fighter" veteran Alex Chambers to kick off the pay-per-view while heavy handed strikers Ross Pearson and Paul Felder cap off the prelims airing live on FOX Sports 1.
