Shields - known for his work with the likes of Mike Tyson and Evander Holyfield - currently trains middleweight world champion Jermall Charlo.
Ronnie Shields is a former professional boxer who fought in the featherweight division and is currently a boxing trainer.
He is the coach of reigning middleweight world titlist Jermall Charlo and also trains former Pound for Pound star Guillermo Rigondeaux, Erislandy Lara and Brian Vera.
Shields is considered as one of the world's best trainers in the sport and works at the Plex Boxing Gym in Stafford, Texas.
Will Shields train Anthony Joshua?
Joshua surrendered his WBA, IBF and WBO titles to Usyk in an underwhelming performance that saw criticism aimed towards current trainer Rob McCracken.
Hearn said: "I think AJ will make an announcement when camp starts, which I guess will be end of January, early February.
"But he's worked hard to get it right. A lot of people have said, 'do you think it's risky to bring in a new trainer?' I flip that and say, 'do you think it's risky to not be comfortable with your setup or your surroundings?'"
Ronnie Shields and Jermall Charlo
Jermall Charlo is regarded as one of the best fighters in the world and currently owns the WBC middleweight world title. An undefeated two-division world champion, Charlo's aim is to face boxing's biggest star in Canelo Alvarez.
Charlo had been linked to facing David Benavidez with the winner in line to face Canelo but Shields ruled it out.
"Canelo came out there today and said that he wants to fight Caleb Plant and then Jermall Charlo.
"So why would Jermall need to go fight David Benavidez to get Canelo? What sense does that make?
"Why does he need Benavidez when we're already going to get Canelo? You got to stick with what makes sense.
"It's a fight that fans want to see, of course," said Shields about a fight between Jermall and Benavidez. "Fans want to see good boxing, but at the same time, this is a business.
"So if you don't have to go through him [Benavidez] to get to him [Canelo]? Why go through him when we don't have to?"

The clash is the most lucrative heavyweight fight of all-time when it pay-per-view buys with 1.95 million sales in America.
Other fighters he has trained with includes Holyfield, Vernon Forrest, Pernell Whitaker, Arturo Gatti and Juan Diaz.
