UFC 191 results: 'Johnson vs. Dodson 2' full play-by-play recaps for Fight Pass 'Prelims'

Ultimate Fighting Championship (UFC) returns to the fight capital of the world, Las Vegas, Nevada, for what is sure to be an action-packed UFC 191 pay-per-view (PPV) later tonight (Sat. Sept. 5, 2015).

Flyweight champion Demetrious Johnson 22-2-(1) aims to defend his belt one more time against familiar foe and No. 1 contender John Dodson (17-6) in the night's headliner. Both men are no strangers to each other, having fought initially at UFC on FOX 6 in Jan. 2013 (full fight here), and have shared unkind words as of late.

Preceding the main event mayhem is a nostalgic tussle between two longtime Heavyweight contenders as Andrei Arlovski (24-10) attempts to wrangle two-time UFC champion Frank Mir (18-9). "The Pit Bull" and Mir have seen their fortunes change after horrendous losing streaks and now find themselves square in the hunt for a title shot ... if they win.

However, before the big boys get to throwing down, fight fans can immerse themselves in a set of six "Prelims" bouts, which start at 7 p.m. ET on Fight Pass, before transferring over to FOX Sports 1 at 8 p.m. ET for the remaining four.

Below are the live results recaps for tonight's two Fight Pass "Prelims" tilts:
