Floyd Mayweather will look to increase his reputation as the pound-for-pound world number one when he enters the ring with Marcos Maidana.
The American remains unbeaten but faces a tough task against Maidana, who has backed himself to cause an upset and dismantle ‘Money’s record.
Mayweather opted for the Argentinian over a scheduled bout with Amir Khan, who will instead fight Luis Collazo at the event.
Here’s all the important information ahead of the bout, including recent form and betting odds.
When and where is the fight?
The fight takes place on May 3, with the action getting underway late on Saturday night and going into the early hours of Sunday morning.
It will be staged in Las Vegas at the MGM Grand Hotel and Casino and will be for Mayweather’s WBA and WBC world welterweight titles.
Mayweather vs Maidana will be a co-main event alongside the Amir Khan vs Luis Collazo bout.

Wasn’t Khan supposed to be fighting Mayweather?
The Brit signed a contract in December, that he hoped would set him up for a super-fight showdown with Mayweather.
However, two months later, the American launched a social media campaign asking fans to decide which of Khan and Maidana he should take on in his next bout.
Interestingly, Khan came out on top in the vote but heard nothing from Mayweather, who instead opted for Argentine Maidana.
Mayweather has since said: “Maidana deserves the opportunity. He’s a champion with an 80 percent knockout ratio. He deserves this fight.”

Mayweather – The 37-year-old hasn’t fought since September 2013, when he defeated Saul Alvarez, courtesy of a majority decision.
He also enjoyed points victories over Robert Guerrero and Migiel Cotto and you have to go back to 2011 for his latest knockout, a fourth-round stoppage of Victor Ortiz.
One of his most famous successes – from a British perspective – was against Ricky Hatton in 2007, where he won with a technical knockout.
Other high-profile names to fall to Money, include Oscar De La Hoya and Juan Manuel Marquez.
Maidana – The Argentine shouldn’t have too much ring-rust to shake off, with his last bout coming in December last year.
Maidana defeated Adrien Broner with a unanimous points decision, six months after a technical knockout win over Josesito Lopez.
His last defeat came against Devon Alexander in Missouri, while back in 2010, the 30-year-old lost on points to the man he pipped to this fight – Amir Khan.
Mayweather is the strong favourite for the bout, with Paddy Power offering 1/16 for him to continue his unbeaten streak.
You can get around 15/2 for Maidana to upset the apple cart in Las Vegas, with a draw available at 25/1.
For the WBA and WBC champion to win on points, a price of 4/6 is on offer, while a knockout success is at 8/15.
It is 9/1 for the Argentine to knockout his illustrious opponent – for the first time in his career – with a points success at a staggering 20/1.
