Floyd Mayweather has once again announced his retirement after his 50th win, following a 10th round stoppage of McGregor in Las Vegas.
The 40-year-old boxer ended an absence of almost two years from the ring, to face Irish UFC star Conor McGregor.
However, Mayweather has vowed to stand by his decision after surpassing Rocky Marciano’s record.
“Rocky Marciano is a legend and I look forward to going down in the hall of fame some day,” Mayweather told Showtime.
“This is my last fight ladies and gentlemen, my last fight. Tonight was my last fight for sure.
“I chose the right dance partner to dance with. Conor McGregor, you’re a hell of a champion and to the country of Ireland, we love you guys.”
“He’s a tough competitor and I think we gave the fans what they wanted to see,” said Mayweather. “I told them that I owed them for the [Manny] Pacquiao fight. I must come in straight ahead and give the fans a show, and I think that’s what I gave them.
“He was a lot better than I thought he was. He used different angles. He was a tough competitor, but I was the better man tonight.
“Our game-plan was to take our time, go to him, let him shoot all his heavy shots early and then to take him out at the end, down the stretch.
“Well, if I’m not mistaken, I guaranteed everybody that this fight wouldn’t go the distance. Boxing’s reputation was on the line. Boxing’s a hell of a sport, MMA is a hell of a sport.”
