Both men will turn professional for the bout, which will serve as the co-main event to Demetrius Andrade’s middleweight title fight with Luke Keeler.
The fight will be shown live on DAZN in the United States, with television details for the United Kingdom yet to be announced.
Paul, 22, is the most viewed internet celebrity across the US with over 36m views across YouTube, Instagram, TikTok and Twitter.
“Coming into the sport of boxing as an undefeated champion amongst my peers, it’s my duty to set the bar as high as possible for others looking to cross over into the sport,” Paul said in a DAZN press release statement.
“This is more than a fight to me. It’s a chance to show the world that anyone with a dream, vision, and the right work ethic, can overcome adversity and shine on the brightest stage.”
Gib is meanwhile a British YouTuber who rose to fame recording himself playing the video game Fifa and starred on the initial KSI vs Logan Paul undercard, defeating Jay Swingler via unanimous decision.
“After six months of Jakey ducking, the fight is finally going down,” said Gib.
“He had no choice of his opponent, I chose him. Since my last fight I have been training nonstop and January 30 in Miami, I will end the fight in devastating fashion and will have my hand raised in front of his country, family and friends. Jake Paul is going to be my walking, talking ad for the rest of his days.”
Hearn meanwhile confirmed that both men would turn professional for the fight, meaning they will box without protective headguards.
“January 30 in Miami just became a whole lot bigger,” Hearn said.
“After the huge success of KSI vs. Logan Paul 2 which broke broadcast numbers worldwide and also got nominated as Ring Magazine ‘Event of the Year,’ I’m delighted to add Jake Paul vs. Gib to our world championship tripleheader on Super Bowl weekend in Miami, live on DAZN.
“Same rules apply, 10-ounce gloves, no headguards and both going through the full professional protocol.”
