Former WBA "regular" champion Mahmoud Charr is taunting Tyson Fury to finalize a fight with him.
Fury, the reigning WBC heavyweight champion, named Charr as a backup opponent if a potential defense against Anthony Joshua fell apart.
Earlier this week, Fury became annoyed with Joshua not signing a recently issued contract and declared the fight was "off" - and named Charr as the next opponent of choice.
Charr is now pressing Fury to get a deal done.
"The lumberjack is coming for you, Habibi. Focus on the belt, focus on the belt. You big dosser! Fury, you are the sh!t as Anthony Joshua. A man is a man. When you say Joshua is out, he is out. You told everyone you want to fight me [and] now we are like a duck. Take the fight," Charr said.
However, Fury has now given Joshua additional time to get a deal finalized.
"My promoter Frank Warren convinced me to let Queensberry carry on negotiating with your team this week, despite me knowing that you were never going to do this fight. So the deadline was Monday. I allowed Frank to continue doing meetings with your team and your broadcasters and all that. Now we have BT, DAZN and ESPN all on the same page," Fury said.
"They are happy with everything, they are all ready to rock and roll. You guys ask for a lot of stuff, you want to be co-promoters when you're a voluntary challenger. Guess what, I said give it them, let them be co-promoters. You wanted full transparency, even though you're not an equal shareholder in this party. You know what I said?
"Give them full transparency, I've got nothing to hide, I'm not trying to rob anybody, I've not robbed anybody of a penny in my life. So now you've got full transparency, everything is clean and fair. Now Joshua, the ball is really in your court son."
