Which boxer has the better knockout ratio, Anthony Joshua or Daniel Dubois?

At the time of writing, Anthony “AJ” Joshua is scheduled to fight Daniel “Dynamite” Dubois for the IBF World Heavyweight title at Wembley Stadium, London on September 21, 2024. Indeed, the eagerly-anticipated clash is expected to set a post-war record for attendance at a British boxing event, surpassing the 94,000 achieved when Tyson Fury fought Dillian Whyte at the same venue on April 23, 2022.

Of course, Joshua, 34, is a two-time unified world heavyweight champion boxer and, since losing, by split decision, to unbeaten Ukranian Oleksandr Usyk at the Jeddah Superdome on August 20, 2022, has beaten Jermaine Franklin Jnr., Robert Hellenius, Otto Wallin and Francis Ngannou, with only Franklin Jnr. Lasting the distance, to earn himself another title fight. He currently boasts a 28-3-0 career record, including 25 knockouts, which gives him a knockout ratio of 89.29%.

Dubois, 26, has been knocked out twice in his 23-fight career, by compatriot John Joyce in November 2020 and Usyk in August 2023, but his 21-2-0 record nonetheless includes 20 knockouts, giving him an impressive knockout ratio of 95.24%. Indeed, on June 1, 2024, he achieved his biggest win to date, an eighth-round technical knockout of hitherto unbeaten Croatian Filip Hrgovic at the Kingdom Arena in Riyadh, Saudo Arabia to win the vacant IBF Interim World Heavyweight title.

Just over three weeks later, Dubois became full IBF World Heavyweight champion after Usyk was forced to vacate the belt, in a move that the hitherto undisputed heavyweight champion described as “my present” to the two British fighters. Joshua is long odds-on to dethrone Dubois, but the latter is “a bigger puncher”, according to promoter Frank Warren, so the fight may not be as one-sided as the odds suggest.
