Ultimate Fighting Championship color commentator Joe Rogan, like a majority of hardcore mixed martial arts fans, will be tuning in for the upcoming UFC 207 pay-per-view event on Dec. 30, 2016, inside T-Mobile Arena in Las Vegas, Nevada. That's because former women's bantamweight champion Ronda Rousey , still considered to the the biggest name in UFC , will make her first appearance since Holly Holm stiffened her at UFC 193 in Australia.
