Demetrious Johnson vs John Dodson 2 staredown pic, video and more from UFC 191 media day in Las Vegas

Ultimate Fighting Championship (UFC) Flyweight Champion Demetrious Johnson and his most heated rival, John Dodson, went nose-to-nose again this afternoon at a media day to promote their rematch in the main event of UFC 191, which takes place inside MGM Grand Garden Arena in Las Vegas, Nevada, this Saturday night (Sept. 5, 2015).

And "Mighty Mouse" was all business. Dodson? Not so much.

Neither were former Heavyweight champions Andrei Arlovski and Frank Mir, who could barely keep straight faces ahead of their pivotal co-main event match that is more than one decade in the making.

Noticeably absent from the festivities was No. 1-ranked Light Heavyweight contender Anthony Johnson, who takes on Jimi Manuwa in a hard-hitting 205-pound showdown. Perhaps it's because of this; regardless, Paige VanZant and Alex Chambers happily filled the void.

Weigh ins tomorrow should be fun!
