The short clip, pieced together from Joshua’s fights were he was either wobbled or dropped, was subject of an official complaint by Sky over the weekend.
A few of the extracts were taken from Sky Sports televised bouts and have subsequently led to the video been hauled off some social media channels.
Duco’s offering, which claims to show SIX fighters who have hurt Joshua or put him on the canvas, has already been shared widely in the boxing community.
Sky haven’t taken too kindly to their star fighter seemingly being treated this way by representatives of one of his main rivals as Duco look after the affairs of Joseph Parker.
Both sides are still said to be in contact over a possible unification in March or April as haggling over the split continues. Parker initially wanted 50-50 before dropping to 60-40 and eventually 65-35 in Joshua’s favour.
Promoter Eddie Hearn still believes Joshua is worth more in the fight, which has since led to Parker throwing in a rematch clause for good measure.
If the pair eventually do get it on during next spring, the video is sure to be a topic of conversation during any media gatherings to promote the fight.
