Tickets for boxing's richest ever fight are still not for sale - but fans are going to be charged admission for the weigh-in for the first time in the sport's history.

Floyd Mayweather vs Manny Pacquiao in Las Vegas on 2 May will break every pay-per-view record in boxing history and could fetch more than $300million.

But fans will more than likely miss out on seeing the fight live. The MGM Grand has a capacity of 16,500 but just 1,000 tickets are expected to go on general sale.

Promoter Bob Arum cut a news conference short before questions about the tickets could be asked.

There is already a thriving re-sale market with one New York broker offering tickets for as much as $87,500 (£58,630) for tickets that had a face value of between $1,500 and $7,500.

However, for the first time in boxing's history you can buy tickets for the pre-fight weigh-in - although the move has been made in the interests of safety rather than for profit.

With more than 200,000 people expected to arrive in Las Vegas just for the fight, official events will need to be monitored.

All revenue from the weigh-in will be donated to charities picked by the two fighters.
