Hearn revealed last month that Las Vegas was the preferred option, despite interest in Dubai, Nigeria and Cardiff, and it now looks all but certain that the second fight will go stateside.
Both Hearn and Joshua have been spending time in the Nevada city and the Matchroom boss reveals that he has met with representatives of MGM and the T-Mobile Arena as he looks to try and finalise the rematch. Speaking to Sky Sports News HQ, Hearn said: "I've been in Vegas with AJ, officially applying for my Nevada boxing license to promote there and that went well.
"I met with the MGM and met with the T-Mobile Arena, Vegas is the front runner and November 11 is the date that is pencilled in. "It will probably take a couple of weeks to get everything over the line, but I believe Klitschko will take this fight and believe Vegas will be the one.
"AJ has been over there for about 10 days and has enjoyed himself and got to know the area a little bit. "The amount of British fight fans that would travel there, it will be a momentous occasion and one that we will savour for a long time so fingers crossed it's a party in Las Vegas on November 11."
