(BBC) – Promoter Bob Arum is still unable to explain why there are no tickets on general sale for the super-fight between Floyd Mayweather and Manny Pacquiao in Las Vegas on 2 May.
The MGM Grand holds 16,500 but only about 1,000 tickets are expected to be made available to the wider public.
Contracts with the MGM Grand remain unsigned, while tickets are also not on sale for other venues across Las Vegas.
Arum cut a news conference short on Monday before questions could be asked.
Meanwhile, it was announced on Tuesday that Kenny Bayless, who has refereed many contests involving Mayweather and Pacquiao, will be the third man in the ring on fight night.
