What happened: Ariel Helwani announced Wednesday's edition of his MMA program will feature actor O'Shea Jackson Jr., former UFC heavyweight champion Junior dos Santos, PFL's John Martin, and Jake Babian as on-air guests. The host promoted the live broadcast on social media, continuing a busy week of guest bookings.

Why it matters: The booking continues Helwani's run of mixing celebrity, executive, and fighter voices on the same program, a format that has driven the show's standing as a primary MMA media destination. Dos Santos's appearance is notable given his ongoing role as a veteran ambassador for the sport, while Jackson Jr. broadens the show's crossover reach into Hollywood.

What to watch: Watch for any news lines that emerge from the dos Santos or PFL segments, particularly around upcoming PFL cards or veteran fighter commentary on the current UFC landscape.
