Floyd Mayweather's preparations for his super-fight with Conor McGregor appear well underway after he flaunted his ripped physique in Las Vegas.

The boxing bout against the UFC superstar will take place at the 20,000-seater T-Mobile Arena in Sin City on August 26.

And after recent rumblings coming out of the McGregor camp, most notably that he 'whimpers like a girl' when he is punched in the body, it appears Money's side of things are going more smoothly.

The 40-year-old showed off his well-defined abs as he joked and relaxed in REHAB Beach Club in Vegas, with the bout just under three weeks away.

And the boxing veteran, who holds a record of 49 wins and no losses, has made the brutal prediction that he will knock Conor McGregor out come fight night to bring up his half-century of victories.

He has enjoyed his downtime during his preparations, even finding some spare time to show off his impressive basketball skills last week.

But make no mistake, Mayweather is in full training for the bout, which is expected to be one of the richest fights in combat sports history.

The two fighters have traded insults and threats during a four-city, four-day publicity tour last month in what has become a fiery exchange.

And it will come to blows when the pair step in the ring for one of the most eagerly anticipated fights of a generation.
