What happened: Johnny Walker meets Waldo Cortes-Acosta in the heavyweight main event of UFC Fight Night 293 in Las Vegas. Action begins with early coverage at 5 p.m. ET across a 14-bout card.

Why it matters: Walker enters with a 23-pound weight deficit after scaling in at 239 pounds against Cortes-Acosta's 262. A win establishes footing in the heavyweight ranks and tests his agility against a heavier puncher.

What to watch: The 14-bout card streams live on Paramount+, culminating in the heavyweight headliner later Saturday evening.
