Following his Commonwealth title triumph in 2014, Warrington signed a five-fight deal under the Matchroom banner.
"Josh is the biggest ticket seller in the country right now, and we have an opportunity to do something very big in Leeds," Hearn said at the time.
However, in 2016, a new contract between both parties could not be agreed and Warrington turned to Hall of Fame promoter Warren. Together, they enjoyed huge success beginning with victory over Martinez, Selby, Frampton, Galahad and Takoucht.
In a shocking turn of events, Warrington and Hearn were reunited in 2020. Speaking to Planet Sport, Hearn revealed he had got his man back on an initial three-fight deal.
"I feel like I'm getting him back in his absolute prime, 29, No.1 featherweight in the division, fanbase better than ever, fresher than ever as a fighter and I'm excited about what's ahead."
"Three fights initially [with Warrington]. I expect him to end his career with us, there's a lot more than three fights but I've never been one to do three fights, five-year deals.
"When I've got a relationship with someone like Tony Bellew and Kell Brook, they were fight-by-fight not because you worry about the future but you got that relationship where you trust them."
Warrington's next three fights will take place on Sky Sports in the UK and DAZN in America, Canada and Spain.
