The snapshot above counts UFC appearances only. The career table shows every recorded professional bout across all promotions, so pre-UFC results remain visible without being mistaken for UFC results.
Source and correction standard
Roster status and activity are checked against Roster Watch. Ranking labels come from the official UFC rankings snapshot dated August 11, 2026. Announced opponents are dated because cards can change.
