Fabio Wardley achieved the biggest win of his career, defeating Joseph Parker to set up a world title shot against Oleksandr Usyk.
In a thrilling contest at the O2 Arena, Wardley demonstrated his toughness by withstanding several huge punches from Parker before forcing the referee to stop the bout in the 11th round.
The WBO had ordered Parker to face undisputed world heavyweight champion Usyk in July.
Parker, who was world champion in 2016, put his mandatory challenger status on the line against Wardley, who was still involved in white-collar boxing at that time.
Parker had promised to be a "different level" to the 30-year-old Wardley, and this seemed to be the case for much of the bout in London.
