Keith Thurman lost his most recent major fight against Sebastian Fundora on March 28, 2026, in Las Vegas, via unanimous decision.

What happened in the Fundora fight

  • The bout was a 12‑round welterweight main event broadcast on pay‑per‑view.
  • Fundora, the younger and taller pressure fighter, used reach and activity to outwork Thurman over the second half of the fight.
  • All three judges scored it for Fundora, giving him the clear decision win and keeping Thurman from a comeback to the elite‑contender tier.

Context from Thurman’s recent record

  • Before this, Thurman had bounced back from his loss to Manny Pacquiao with a strong unanimous‑decision win over Mario Barrios in 2022.
  • His earlier career highlight was a razor‑thin unanimous‑decision victory over Shawn Porter in 2016, which many fans still talk about in online forums.

If you meant a different Keith Thurman fight (e.g., Pacquiao or Porter), just say which one and I’ll break that result down in the same style.
