What happened: The bout was waved off after one round following a doctor's check, giving Cesar an official TKO over Joshua Perreira on the live ONE Fight Night 48 card. The stoppage came before the second round could begin on ONE's Prime and international TV broadcast.

Why it matters: Doctor stoppages settle a fight without scorecards, making the ringside medical call the decisive moment. An opening-round finish also gives Cesar a fast result on a card carried in more than 195 countries.

What to watch: Cesar's next booking becomes the immediate question after a quick finish, while Perreira awaits the standard post-fight medical process.
