If you intend on watching Floyd Mayweather take on Andre Berto tonight (Sept. 12, 2015) at MGM Grand Garden Arena in Las Vegas, Nevada, it may well be an historic moment in boxing.
Should Mayweather prevail, he would move to 49-0, matching the record of Rocky Marciano, the post-World War 2 Heavyweight fighter who walked away from the sport in 1955 going undefeated in his career.
"Money" claims this will be his last fight as well.
Of course, we've heard that story before. Back in 2007 after defeating Oscar de La Hoya to take the WBC Light Middleweight title, then-30-year-old Mayweather said he planned to retire, saying he had nothing left to prove.
