Former two division world champion Anthony Joshua sent a firm warning regarding a potential fight with fellow Olympian Joe Joyce.

Joshua suffered a career setback when he was outboxed over twelve rounds last September, in his showdown with Oleksandr Usyk at Tottenham Hotspur Stadium.

The British star was hoping to reclaim the WBO, IBF, WBA, IBO titles by facing Usyk in a contracted rematch, but that scenario is now on hold - with Usyk returning to his homeland of Ukraine to assist with the military resistance against the ongoing attack by Russia.

Frank Warren, promoter of Joyce, would love to get his boxer a fight with Joshua.

"I think the public would definitely buy into AJ-Joe Joyce. We’d make that in a heartbeat, Joe would fight him in a heartbeat. What a great domestic bust-up that is, let’s get our heads together and we’ll get that done," Warren said to IFL TV.

Joyce was in action in July of last year, when he stopped world title challenger Carlos Takam in six rounds at Wembley Arena.

Warren believes a Joyce vs. Joshua clash would be a tremendous box office hit among domestic fans. Joyce and Joshua are very familiar with each other from their days in the amateur ranks with Team GB.

Joshua took to social media to respond to Warren's take on Joyce - and he also responded to promoter Dmitriy Salita, who recently stated that his heavyweight, Otto Wallin, was capable of beating the British star.

According to Joshua, he stopped Joyce in a single round when they sparred in the past - and he believes that he would stop him in one round right now.

"Lol ok … I've shared this ring with most people you see in the heavyweight division today! I boxed Otto Wallin twice as youngsters [and] I boxed Joe and stopped him in 1 round. I'd do the same thing today! Ain't nothing changed," Joshua stated.
