LAS VEGAS – The biggest event in boxing history is rapidly turning into its greatest embarrassment.

And that's saying something considering the long and mostly sordid history of professional boxing.

It's less than two weeks before Floyd Mayweather Jr. and Manny Pacquiao are scheduled to step into a ring at the MGM Grand Garden on May 2, but incredulously, tickets to the fight aren't on sale yet. Nor are the approximately 50,000 closed-circuit seats in Las Vegas that are supposed to be available for purchase.

Combined, the fighters are expected to collect upwards of $300 million in prize money between them. The bout is expected to easily surpass every financial record ever kept, even adjusting for inflation. Pay-per-view sales could, for the first time, threaten three million.

If there is an event, of course the rich and the famous won't have any worries about accommodations and tickets, even though there unquestionably will be a lot of very rich noses seriously out of joint when they discover their $1,500 tickets are in the upper reaches of the arena.

The average boxing fan, the one who kept this sport alive and kicking through the many dark years, is being hit hardest by this debacle.

Perhaps most frustrating for all fans: the reason the tickets are not on sale as of yet is anybody's guess, since those in a position to know are either pointing fingers in opposite directions, engaging in double talk or choosing not to speak publicly at all.

Top Rank CEO Bob Arum placed the blame squarely on Mayweather's adviser, Al Haymon.

Mayweather Promotions CEO Leonard Ellerbe said Haymon isn't involved in things like ticketing and the deal between the venue and the promoters. Ellerbe pointed the finger back at Arum, saying, "He just can't stomach the fact that he's not the lead promoter."

Haymon doesn't speak to the media and nobody other than his closest confidantes truly knows what he thinks or, more importantly in this case, what his role, if any, might be.

Nobody at MGM Resorts International, including Chairman & CEO James Murren, president Bill Hornbuckle and, most significantly, Richard Sturm, the company's president of entertainment and sports, have been made available to the media or even issued a public statement in explanation.

It's a farce, and it's turning what could be a great sporting event into a question mark. Millions of dollars are floating out the window each day that passes without tickets on sale.

There are only so many feasible explanations:

• One possibility, pushed hard by Top Rank, is that Haymon is orchestrating some maneuver behind the scenes to obtain tickets he could then sell on the secondary market.

• A second possibility is that Mayweather Promotions isn't prepared to accept the responsibilities of staging an event of this magnitude. Ellerbe scoffs at the notion that his team is behind the issues and said it successfully organized Mayweather's recent fights fully on its own. He said despite Golden Boy Promotions' involvement in Mayweather's last few fights, his company successfully ran them start to finish.

• Another explanation is that MGM executives remain angry at Arum for highly incendiary comments Arum made about Sturm prior to the Pacquiao-Timothy Bradley rematch at the MGM Grand in 2014.
