One of the biggest nights in boxing history is edging nearer as Floyd Mayweather and Conor McGregor prepare to settle what has to be one of the most bitter rivalries in Las Vegas on August 26.

The fight is still a few weeks away, but already anticipation levels have rocketed to unprecedented levels.

Tickets for the bout, which will be held at the T-Mobile Arena, sold out in a matter of minutes, with the cheapest going for a cool £8,000. 

Both fighters have clicked into high gear as they take their brutal training regimes to the next level.

One thing that can not be doubted is that both men will be in the shape of their life when they step into that ring.

McGregor, who is undoubtedly the underdog having never boxed professionally in his life, is reportedly holding nothing back during sparring sessions and will come out all guns blazing when the famous Las Vegas lights are glaring down at him.

Mayweather, however, is one mighty seasoned campaigner.

The 49-0 global superstar has seen it all and is not easily phased, and he again is proving that the only thing that matters to him is what happens on fight night.

Mayweather was filmed at a recent party looking cool, calm, and not to mention, absolutely ripped.

The 41-year-old was entirely carefree as he made merry with the other people present at the party, taking what looked to be a brief break from training.

The American proudly showed the pristine physical condition he is in ahead of the fight, showing off a set of abs that you could probably grill a steak on.

Watch below.

Look out, McGregor. Not bad at all for a 40-year-old.

However, you can be sure Mayweather was back grafting in the gym soon after his little break.

Mayweather will be taking nothing for granted against an unpredictable McGregor, who is desperate to knock the American clean out.
