Promoter Eddie Hearn says Kell Brook's world title eliminator against Rafal Jackiewicz in Sheffield on Saturday night could be his last in the UK before he hits America.
Brook puts his WBA Inter-Continental welterweight title on the line against the former European champion at the Ponds Forge International Sports Centre as he continues to knock on the door of the major players in the division.
The unbeaten 25-year-old (24-0, 16 KOs) has been linked with a number of blockbuster fights in the new year and Hearn, who was Stateside last week for Darren Barker's big night with Sergio Martinez, believes he could be ready to make his American debut early in 2012.
"Every time I'm in America I'm bombarded with questions about Kell," said Hearn.
"We have already had some interesting offers and it's inevitable that Kell will make his mark there soon. Kell has that crossover appeal, superstar potential that will in time make him a global star.
"First thing first he has to deal with Rafal and do it convincingly - then we are going after that world title."
