UFC 170: Rousey vs. McMann Live Streaming Weigh-in Video

Headlined by women's bantamweight champion Ronda Rousey and fellow Olympian Sara McMann, UFC 170 is set to go down this weekend.

Rousey has successfully defended her UFC title in back-to-back bouts, but McMann could be her toughest test stylistically. The former freestyle wrestling silver medalist could be the first fighter who is capable of forcing Rousey to stand.

Additionally, Daniel Cormier will make his light heavyweight debut on Saturday. "DC" was originally scheduled to meet Rashad Evans in the co-main event, but he'll now meet replacement opponent and UFC newcomer Patrick Cummins in what looks to be a warm-up.

Furthermore, welterweight contenders Rory MacDonald and Demian Maia will battle to get back into the win column. Despite their recent losses, both fighters are very much in the hunt for a shot at the currently vacant 170-pound championship.

The UFC 170 weigh-ins will be held on Friday at 7 p.m. ET. When the weigh-ins begin, live streaming video will be available on the video player above.
