Despite spending two months in prison for punching former long-term partner Josie Harris, Floyd Mayweather Jr has wasted no opportunity to deny and downplay the events of September 9, 2010. In fact, boxing's biggest draw tells a very different version of what happened on the night that ultimately led to his incarceration last summer.

Harris has refused to detail the attack until now, choosing instead to relocate with the three children she shares with Mayweather to Valencia, California.

However, after a scene in Showtime's "30 Days In May" – an hour-long documentary used to promote

The boxer who pummeled opponents with his words as well as with his fast fists rarely talks these days, and his dazzling footwork is a memory frozen on video tape and in the minds of millions of admirers.

But the spirit and sparkle in 71-year-old Muhammad Ali's eyes live on through a 30-year struggle against the effects of Parkinson's disease, which has stricken about one million in the United States and six million worldwide.

His daughter, Maryum (May May) Ali, said the man who famously dubbed himself "The Greatest" gets a big kick from watching old footage of himself.

"That's his favorite

Dear Mr Harrison,

I will keep this short and sweet. In fact, I’d like it to take you less time to read this than it took Deontay Wilder to drop you in Sheffield on Saturday.

So, let me just set my timer to 70 seconds….........................................and go:

Please retire. Please, please, please, please retire.

I realise getting dumped on your backside by every untested heavyweight prospect is probably a profitable living, but surely at 41 you have enough money stashed away to stop the embarrassment?

Fraudley, A-Farce, Audrey, Harris-down. Haven't you had enough of it all? And let's

Diaz drops Khan in round four (Getty Images)

Amir Khan is a curious case in a very curious sport.

As one of Britain's most exciting fighters in a long time, a trans-Atlantic hit and an Olympic hero, one would expect the Bolton lad to be more nationally-embraced than he is.

Instead, in his first bout on UK soil in two years, Khan had many people riding his choice of opponent, predicting a quick knockout defeat, or even hoping he a prospective third loss in four would compel him to retire.

Unfortunately that is the price that comes with success, especially if you have also fallen on your sword a few times

Argentine boxer WBC Middleweight Champion Sergio Martinez

When a wobbly Sergio Martinez withstood a furious last-minute assault from Julio Cesar Chavez Jr. in Las Vegas last September to win the WBC middleweight championship, hundreds of his Argentinian compatriots poured out of the stands at the Thomas & Mack Center and rushed toward the ring in celebration.

On Saturday, Martinez will repay his countrymen for their support by making a title defence against Martin Murray in front of a sell-out crowd of more than 50,000 at Club Atletico Velez Sarsfield in Buenos Aires.

It will amount to a celebration of Martinez's greatness, but it should rightly be

Zab Judah (AFP)

On a card filled with talented boxers, it's almost amazing to think that all these years later, the most purely talented of them just still might be Zab Judah.

Judah will challenge champion Danny Garcia Saturday at the Barclays Center in Brooklyn for the WBA-WBC super lightweight titles.

It's no surprise that Judah, now 35, a Las Vegas resident and far more mellow than the angry Brooklynite he once was, is fighting in a significant bout with multiple titles on the line. He has had multiple title reigns at 140 pounds and was, for a while, the undisputed welterweight champion.

For all he's

Floyd Mayweather Jr. works out at the Mayweather Boxing Club in Las Vegas, Nevada (AFP)

Two short emails released to the media by Keith Kizer, the executive director of the Nevada Athletic Commission, seemed to ignite yet another dispute between powerhouse promoters Top Rank and Golden Boy.

On Tuesday, Top Rank formally requested the date of September 14 for a pay-per-view fight at the Thomas & Mack Center in Las Vegas between Juan Manuel Marquez and Timothy Bradley. As soon as that was released, though, Golden Boy CEO Richard Schaefer said his plan was to have Floyd Mayweather Jr. fight on that date at the MGM Grand Garden.

Both promoters, as well as the casinos, covet the

Canelo Alvarez (Golden Boy)

Rare is the athlete who becomes one of his sport's biggest attractions without the accompanying accomplishment on the field of play.

Yet, while Canelo Alvarez is one of the four or five biggest draws in boxing, his accomplishments have yet to match his popularity.

Those doubts will be erased on Saturday after he fights Austin Trout in the main event of a sold-out card at the Alamodome in San Antonio in a WBA/WBC super welterweight unification match.

A win over Trout would vault Alvarez into truly elite status. A loss, though, could confirm suspicions that Alvarez has been coddled on the way
