If Joshua wins the IBF belt, he will be one of four who have become world champions in the heavyweight class in boxing three times. The three legends who have achieved this feat so far are Muhammad Ali, Evander Holyfield, and Lennox Lewis.
Joshua would, in that case, be crowned the king of heavyweight boxing again in front of a large audience. Tonight's match between the two Brits will be watched by 96,000 fans on site at Wembley in London.
The 34-year-old Joshua is no stranger to large audiences, not least at Wembley. It was, after all, there that he defeated Volodymyr Klytjko to become world champion for the second time.
For his opponent, the 27-year-old Daniel Dubois, the scene is not as familiar. This is the first time Dubois will defend his IBF title and his second world championship match.
If Dubois, with 21–2 in matches, including 20 wins by knockout, were to win, it would mean an enormous boost to his career. He believes the match gives him the opportunity to solidify his status as world champion, with what would be the biggest win of his career.
I have to show who I am and get the world to respect me, says Dubois.
Joshua, with 28–3 in matches, including 25 wins by knockout, has been in this situation many times before. Ahead of the match, the Brit sounds confident.
Dan is meeting someone who is ready to die in the ring, says Joshua at a press conference.
