World champion Billy Joe Saunders has apologised after posting a video on social media in which he advised men how to hit their female partners during the coronavirus lockdown.
The WBO super-middleweight champion, 30, was shown demonstrating techniques on a punch bag.
Briton Saunders later said he would "never condone domestic violence".
He added: "If I saw a man touch a woman I would smash him to pieces myself. Apologies if I offended any women."
In the video Saunders uses a punch bag to explain how to react if "your old woman is giving you mouth" and showing how to "hit her on the chin".
Saunders was close to finalising a deal to face Mexico's Saul 'Canelo' Alvarez in Las Vegas on 2 May before the outbreak of the coronavirus pandemic.
Saunders, who is unbeaten in 29 bouts, held a world title in the middleweight division before moving up to super-middleweight.
He defended his title in a laboured knockout win over Marcelo Esteban Coceres in Los Angeles in November.
In September 2018, Saunders was fined £100,000 by the British Boxing Board of Control (BBBofC) for a social media video that police described as "sickening".
Saunders apologised for the video, in which he told a woman he would give her £150 worth of drugs to perform a sex act.
The BBBofC found him guilty of bringing the sport into disrepute and issued a severe reprimand as well as the fine.
