Former unified heavyweight champion Anthony Joshua was upset being knocked out in the sixth round after being down for the third time by IBF Interim champion

LONDON (AP) — Daniel Dubois retained the IBF heavyweight title by knocking out former two-time world champion Anthony Joshua in the fifth round in a dominant first defense of his belt on Saturday.

The IBF heavyweight title is on the line as Anthony Joshua and Daniel Dubois face off. Keep up with live updates from the undercard and main event.

Dubois was elevated from interim champion when then-undisputed champion Oleksandr Usyk was stripped by the IBF, allowing Dubois to become full world champion. After losing a 2023 bout to Usyk, Dubois now faces Joshua in an attempt to prove himself a legitimate world champion and to possibly position himself for a rematch with the recognized best heavyweight in the world.

Promoter Eddie Hearn said Anthony Joshua will want another "big fight" next after the former two-time heavyweight champion vowed to continue despite his shock defeat to Daniel Dubois in London on Saturday.
