Mike Tyson is hoping to fight Lennox Lewis in California.
Tyson's agent Shelly Finkel has told the Los Angeles Times that the former world champion will apply for a boxing licence in California.
The aim is to stage a fight with Lewis at Los Angeles' Staples Center.
"We would very much like to hold the fight there," said Finkel.
Staples Center president Tim Leiweke said: "It's up to the commission. Assuming they approve, yes, we would be interested - but it's such a fluid situation right now."
Tyson had wanted to hold the showdown in Las Vegas on April 6.
But the Nevada State Commission denied him a licence, citing his role in a brawl last week in New York, and his decision not to continue the treatment and medication that had been prescribed for him more than three years ago.
Mogens Palle, the promoter of Tyson's recent bout with Brian Nielsen in Copenhagen, has expressed an interest in hosting the clash in Denmark.
Rodney Berman, whose Golden Gloves Promotions staged Hasim Rahman's upset of Lewis in South Africa last year, is also hoping to stage a title showdown.
