Oleksandr Usyk's case as one of the greatest boxers of all-time grew on Saturday with a fifth-round knockout over Daniel Dubois to reclaim the IBF title and become an undisputed champion for an unprecedented third time.

Usyk, who held the WBA, WBO and WBC heavyweight belts before Saturday's bout, relinquished his IBF title in June 2024, a little more than a month after he became the first boxer since Lennox Lewis (1999) to become the undisputed heavyweight champion with a split decision victory over Tyson Fury.
With his win over Dubois, who had taken the IBF belt after it was relinquished, Usyk became the first male boxer of the four-belt era (since 2007) to be named undisputed champion three times. Usyk was also the undisputed cruiserweight champ from 2018-19.

Usyk (24-0, 15 KOs) is the division's most dominant player in a generation. Making his reign even more impressive is — as Ring Magazine noted on social media — that Usyk has vanquished several of his top opponents on their home soil, including Dubois on Saturday at Wembley Stadium in London.
Oleksandr Usyk is boxing's ultimate road warrior as he has beaten:

Usyk's numbers speak for themselves. And at 38, he's showing no signs of slowing down.
He dominated the much younger Dubois, 27, in his fifth-round knockout. Per Compubox data, Usyk landed 57 of 153 punches thrown (37.3 percent), including 12 of 17 (70.6 percent) in Round 5, while Dubois finished landing 35-of-179 punches (19.6 percent).
During the fourth and fifth rounds, Usyk landed 18 out of 34 power punches (52.9 percent) compared to 7-of-23 (30.4 percent) from Dubois.
Already the greatest heavyweight boxer this century, Usyk inches up the all-time leaderboard each time he enters a ring. With his historic Saturday win, Usyk's legend continues to grow.
