Hong Kong 'not a viable venue'
Bob Arum has counted out Hong Kong as a big-fight venue because Macau pulls in more money from gaming.
"Why do you think all the top fights are held in Las Vegas? It's because it attracts gamblers and that means revenue for the casinos," he said.
"Macau has been described to me as Las Vegas on steroids and it would make sense to have future title fights here. It's highly unlikely to take place in Hong Kong. The money is guaranteed in Macau."
The long-time boxing promoter had his fingers burned before with the ill-fated "High Noon in Hong Kong" in 1994. The event was called off at the last minute because organisers couldn't guarantee the purse for the fighters.
"The company involved [belonging to former film producer John Daly] said they had the money for the fight but it turned out that it wasn't true. It was a mess. It's not Hong Kong's fault. It was Daly's fault," said Arum.
