JAKE PAUL has been called out to a "future fight" with Sonny Bill Williams.
The YouTuber-turned prizefighter recently returned to the gym to begin training for his boxing return.
And it did not take long for Paul, 25, to announce he will be back in the ring in just five months time.
He said on Instagram: "August I'm back baby. Anyone's who's been talking, y'all going to be silenced again.
"I'm knocking y'all the f*** out, no cap."
Responding to the clip, Williams' coach, former middleweight world champion Andy Lee, proposed a bout with the ex-All Blacks star.

Lee, 37, tweeted: "Future fight @SonnyBWilliams vs @jakepaul."
The former New Zealand international, 36, retired from rugby last year and has since focussed on boxing again.
Williams is currently 9-0 and most recently beat Australian rules footballer Barry Hall, 45, in one round.
He has been training alongside heavyweight champion Tyson Fury, 33, and contender Joseph Parker, 30.

Paul meanwhile was last in the ring in December when he knocked out Tyron Woodley, 39, in their late-notice rematch.
Woodley had been beaten on points four months earlier but replaced Tommy Fury, 22, who pulled out injured.
Paul added to KOs over online rival 'AnEsonGib', ex-NBA player Nate Robinson, 37, and retired UFC welterweight Ben Askren, 37.
