DEONTAY WILDER hit out at "daddy’s boy" Andy Ruiz Jr and demanded he accept the fight offer sent his way.
The American pair have been lined up to face each other for some time but Wilder claimed a deal has now been put to Ruiz.
And in a social media video, he implored the former unified champion to take the offer while he can.
Wilder, 37, said: "Let's get this fight on, man. We offered you a hell of a lot of money.
"One thing I don't want, I don't want you to allow others to dictate your career at this moment in time.
You’ve been shaving your legs wrong - my way's faster & gets them smoother
"It's only a short period of time that you have, you've got to man up to your responsibilities because if you allow others to dictate your life at this point in time, you're going to end up with zero, broke my man.
"So make wise decisions. I don't have no more time to wait on you about this situation.
"We offered you a lot of money, I think that you should take it. One thing I don't want you to do though is allow others to dictate your career in this moment of time, bro.
"You only have a limited time left to make as much money as you possible can. Don't allow others to interfere with this.
"You make the decision, it wouldn't be fair to you or your kids that you miss out on zero because you allow others to interfere with your career at this moment in time.

"So think about it bro, let's get this thing done, man. Let's get it signed, sealed and delivered.
"As I said once again, I'm sick and tired of sitting around, man. Let's give the people what they're asking for and what they want.
"Enough is enough, ball is in your court now, baby. Let's get it. I'll see you soon, man."
Wilder has been out of action since October of last year when he knocked out Robert Helenius, 39, in a round.

A month earlier, Ruiz, 33, beat Luis Ortiz, 44, on points but he has also not returned since.
Wilder added more fuel to the fire with his Instagram captioned which took aim at Ruiz's dad.
He wrote: "Stop playing around @andy_destroyer13 and be a man and make your own decisions and not allow your daddy to mess up your last few years #DaddyBoy.
"It's okay to be that but you're a grown-ass man with children depending on you.
"Remember that before it’s too late then you’ll have regrets while your father lectures you on how you should have saved your money lol."
Ruiz simply replied: "Lets goo."
Wilder is also in talks to fight Anthony Joshua, 33, in a Saudi Arabia blockbuster in December.
Meanwhile, Ruiz was linked with facing WBC champion Tyson Fury, 34.
