A controversial Anthony Joshua video has surfaced alleging the champion to have made inflammatory remarks, his promoter reacts.

The boxing world is up in arms in some quarters following a controversial video surfacing.

A clip essentially alleging heavyweight champion Anthony Joshua to have made disparaging remarks towards American heavyweight Eddie Chambers.

Here is the video in question:

Joshua himself has not responded to the video above at this time, but his promoter Eddie Hearn took to social media to address boxing fans on Twitter, denying that it is authentic:

It’s fake – look at spaces between underscore

Joshua has been involved in negotiations for significant fights in recent times involving world heavyweight title unification showdowns between WBC champion Deontay Wilder and WBO champion Joseph Parker.

The heavyweight champion is currently in Dubai enjoying a vacation after recently defeating Carlos Takam via a 10th round TKO at the Millennium Stadium in Cardiff, Wales recently.

A showdown with Tyson Fury has also been mooted for 2018 when Fury returns to the sport of boxing.

At present Fury is awaiting an outcome next month from a UKAD hearing and must obtain his professional boxing license, then have one warm up fight at least before being in line for a Joshua bout.
