Joe Calzaghe and Enzo Maccarinelli will fly to America next week in another bid to woo the US audience.
The Welsh world champions will attend a media gathering in New York on Tuesday.
"This is an excellent chance to build their profile further in the US after last week's wins got great figures on TV there," said promoter Frank Warren.
The news comes as Dane Mikkel Kessler's promoters have stepped up the campaign for Calzaghe to fight him, claiming it is the bout the public is demanding.
A super middleweight unification battle between WBO & IBF champion Calzaghe and WBA & WBC holder Kessler is a possibility, perhaps in Cardiff's Millennium Stadium in February or March.
Joe's popularity in the US is growing all the time and Enzo can be a star because he's so exciting

But that would need more selling to the US public than a bout with a fighter who is well established across the Atlantic, Bernard Hopkins being Calzaghe's preferred option.
To land such an encounter, Calzaghe would almost certainly have to fight in the States, something he has been reluctant to do in the past.
New WBO cruiserweight champion Maccarinelli would, meanwhile, love the chance to fight in America, although that would probably need to be on a Calzaghe undercard.
Bonymaen-man Maccarinelli has named WBC & WBA title-holder O'Neil Bell - acknowledged as number one in the division - as his primary target.
"Obviously Joe is well known in America because of his previous fights on US TV, but his popularity is growing all the time," said Warren.
"I think Enzo has the potential to become a real star as well because he is so exciting to watch.
"He's one of the best punchers in the world and a really nice guy to boot, and now is his chance to kick on from the win over Mark Hobson."
