Warrington has had a number of sell-out fights at the Leeds First Direct Arena in the past two yearsbut Hearn decided against renewing his contracted at the start of this month as the two parties "did not share the same plans".
The 26-year-old is undefeated in 24 featherweight fights and sees the link-up with Warren as an ideal opportunity to set up a world title fight.
“My original dream was to win a British title at the First Direct Arena and now we’ve gone beyond that and won European and International titles,” said Warrington.
“All I want to do now is win a World title and I’ll do anything it takes to do that. I kill myself in the gym every time I fight and I’m determined to make my dream a reality.
“Every fight I have is a World title fight to me and the ultimate goal is to bring a World title back to Leeds and become the first World Champion from the city.
"The buzz around the city is crazy at the moment, they’re craving for a World Champion. I have little old ladies stop me in the street and ask me when I’m going to be fighting at Elland Road.
“Fighting for World title at the home of Leeds United would be a dream come true for me. I just need to keep on winning and keep on dreaming and hopefully that will be the end product of all of my hard work.”
