Anthony Joshua vs Francis Ngannou, billed as Knockout Chaos, was a heavyweight professional boxing match contested between 2-time former unified heavyweight champion Anthony Joshua and former UFC heavyweight champion Francis Ngannou.
Following his impressive stoppage of Otto Wallin in December 2023, Anthony Joshua was linked with IBF number one ranked Filip Hrgović or WBO "interim" titleholder Zhilei Zhang.[1] However in January 2024 it was confirmed that he would face former UFC champion Francis Ngannou, who in his only previous boxing bout scored a knockdown against WBC and Lineal champion Tyson Fury before losing a somewhat controversial split decision.[2] [3]
Before the main event, Israil Madrimov stopped Magomed Kurbanov to win the vacant WBA Super Welterweight belt. This was followed by Nick Ball challenging WBC featherweight champion Rey Vargas. After twice flooring the champion (once appearing to push him before handing a left hook) the bout was ruled a draw with scores of 116–110 for Ball, 114–112 for Vargas and 113–113.[4]

In the chief support WBO "Interim" titleholder Zhilei Zhang faced former WBO heavyweight champion Joseph Parker (WBO: 2nd WBC / WBA: 3rd).
Parker was dropped twice in the bout, once in 3rd with a left hand and once in the 8th with a left-right hook combination. However Zhang's lack of output compared to Parker cost him, as two of the judges scored it for Parker 114–112 & 115–111, with the third having it 113–113.
Joshua dominated the bout, knocking down Ngannou, who switched to southpaw, with a straight right hand (a punch often dubbed as the 'southpaw killer') down the pipe in the 1st round. Ngannou beat the count and reverted to orthodox but was floored again in the 2nd. He again rose to his feet, but Joshua finished the fight with another right hand that left Ngannou flat on the canvas for several minutes afterwards.[5] [6]
Speaking in the ring after the bout promoter Eddie Hearn said "You’re looking at the number one heavyweight in the world, unquestionably. On this form, there is no man in the world that can beat him in the heavyweight division." before stating his desire for Joshua to face the winner of the planned May 18 bout between Tyson Fury and Oleksandr Usyk.[7]
Ngannou later confirmed that he will continue boxing despite the loss. However he dropped out of the top twenty rankings of WBC due to his second straight loss.[8]
