The UFC returned to Las Vegas last week, and this Saturday they'll host the second of five fight cards at the APEX Arena during a packed August.

The main event offers a pair of top-10 heavyweights with highly contrasting styles in a fight no one thinks will go the full five rounds. When you have heavyweights in a small cage, that's always interesting.

Prelims begin at 6 p.m. ET on ESPN+, and the main card starts at 9 p.m. ET on ESPN+.
