A moment of reckoning lies ahead for six UFC stars: champions, former champions, Invicta champions and more. As pound-for-pound great Jon Jones looks to start a new chapter of his personal life, his professional path will again cross with that of reigning champion and bitter rival Daniel Cormier. With the legacies of both men on the line, the light heavyweights train for much more than the rights to a belt. In the co-main event, welterweight champion Tyron Woodley readies to face jiu-jitsu master Demian Maia, who patiently racked up seven straight wins en route to his second UFC title shot. Plus, former Invicta champion Cris Cyborg finally gets her title shot in the Octagon, with current Invicta titleholder Tonya Evinger answering the call to face the feared Brazilian.
