Daniel Dubois shocked the boxing world by defeating former unified champion Anthony Joshua with a fifth-round knockout at Wembley Stadium, in front of a record 96,000 fans. Dubois, defending his IBF heavyweight title for the first time, floored Joshua four times before delivering a decisive right hook. Despite moments where Joshua appeared to rally, Dubois' aggressive strategy and powerful punches dominated the fight from the first round. This victory solidifies Dubois' status as a legitimate heavyweight champion and positions him for future high-profile matches against Tyson Fury or Oleksandr Usyk. Joshua's defeat raises questions about his future in the sport, following another significant setback in his once-dominant career.
