Being hospitalised last week, I missed Sky's the pay-per view telecast of the event in Saudi Arabia in which Anthony Joshua regained his various world heavyweight tille belts.

Unified world heavyweight boxing champion Andy Ruiz Jr has turned down the chance to compete at next year's Olympic Games in Tokyo.

London will witness a ring rarity this weekend, when two Olympic boxing gold medallists collide at the O2 Arena for a professional world championship.

Nelson Mandela was bang on the button when he declared: "Sport has the power to change the world. It has the power to inspire, the power to unite people in a way that little else does. It speaks to youth in a language they understand. Sports can create hope, where there was once only despair. It is more powerful than Governments in breaking down racial barriers. It laughs in the face of all types of discrimination."

Well, was it an accident waiting to happen? The consensus among the fight fraternity was that sooner or later the fallibility of Anthony Joshua’s defence and in particular his jawbone, would be exposed. It is just that no-one expected to happen against a bloke who looked like Humpty Dumpty.
