Logan Paul has confirmed that he is planning to return to boxing and fight Whindersson after the Brazilian called him out.
The YouTube star previously teased a third fight with KSI but that bout now seems off the cards after the pair launched a new drinks business together.
As a result, Paul's next opponent looks set to be Whindersson - full name Whindersson Nunes Batista - who made a bid to fight the American after an exhibition against former boxer Acelino Freitas.
After accepting the call-out in January, Paul was recently filmed confirming his plans to return to the ring, having not fought since facing legend Floyd Mayweather last June.
"Yeah, I will," the 26-year-old told TMZ. "There's this Brazilian guy, his name is Whindersson, who I've got my eyes on."

Paul's clash with Mayweather went the full eight-round distance, and no winner was announced.
In Whindersson's fight, for which he lost more than five stone, he was badly cut by Freitas, but judges eventually called the bout a draw after their eight rounds.
The 27-year-old is also a star on YouTube and Brazil's second-most subscribed-to figure on the platform, also boasting 57 million Instagram followers - more than twice as many as Paul - who is one of the leading social media figures in North America.
Amassing over 3 billion video views, his videos usually centred on the hilarious tribulations of his childhood and growing up.
But now Whindersson is making his name in the world fighting, just like his next potential opponent, who he called out after facing 'Popo'.
He demanded a fight following his draw, having suffered a cut and struggling through the latter stages, and Paul later responded, "Challenge accepted." Whindersson then replied: "Let's do it".
"I thought it was cool to find out what a knockout looks like. A new thing. I've seen everything in this life," he added after his bout against Freitas.
"Now I felt a hand: I almost slept here'. It was quick. People saw it here as if it was the first time I had ever been beaten. It's not [laughs]. It's not the first, nor the last."
Alongside ex-rival KSI, Paul claimed earlier in January that he was retired from boxing while the pair promoted their new brand.
Asked what they do for a living by TikTok star ItsDanielMac, KSI responded: "Well we used to be boxers but we're retired now," to which Paul affirmed, "Yeah."
However, it now appears that the latter will be back in the ring for the first time since the Mayweather meeting to face Whindersson.
