According to Top Rank President Todd duBoef the ticket issue has been resolved, but only about 500 tickets will be available to public when they do go on sale.
The rest will be given to Mayweather, Top Rank and the MGM. By the end of the evening the ticket brokers (stubhub and sites like that) should be flooded with tickets that will be sold far above retail value. No floor seats will be available for public sale because the camps will put many of the tickets they received up for resale.
There should be close to 40k closed circuit tickets available, if you would like to watch the fight at one of the MGM properties. Details on how to purchase those and weigh-in tickets will be forthcoming.
