Nate Diaz vs Conor McGregor 2 full fight video preview for UFC 202 PPV main event

Ultimate Fighting Championship (UFC) is just hours away from its upcoming UFC 202 pay-per-view (PPV) main event, which takes place TONIGHT (Sat., Aug. 20, 2016) inside T-Mobile Arena in Las Vegas, Nevada, headlined by the Welterweight rematch between Nate Diaz and Conor McGregor.

Their first go-round -- which took place in the main event of UFC 196 back in March -- featured a second-round submission win for Diaz after getting knocked around for the better part of round one. The duo were originally expected to headline UFC 200; however, some "Notorious" shenanigans threw a monkey wrench into those plans.

Check out their fight video preview embedded above.
