'Countdown' to UFC 170 full videos replay online for 'Rousey vs. McMann' on FOX Sports 1

The "Countdown" has begun!

"Countdown" to UFC 170 lit up the airwaves earlier this week on FOX Sports 1 to help promote the upcoming pay-per-view (PPV) event scheduled for this Saturday night (Feb. 22, 2014) inside the Mandalay Bay Events Center in Las Vegas, Nevada.

And it's a fight that needs no introduction.

That's because the women will once again break new ground as two former Olympic medalists, Ronda Rousey and Sara McMann, will slug it out in the main event for "Rowdy's" bantamweight belt. Check out an in-depth preview of their weekend title scrap in the video above.

But there's more to the story. Much more.

In light heavyweight action, Patrick Cummins will attempt to turn the mixed martial arts (MMA) world on its head by upsetting the heavily-favored Daniel Cormier, who is done shedding tears at "Durkin's" expense. Elsewhere on the card, Demian Maia battles Rory MacDonald to see who stays relevant in the welterweight title hunt. Check out their "Countdown" videos below.
