Undefeated welterweight Floyd Mayweather Jnr, widely regarded as the world's top pound-for-pound boxer, will return to the ring in September for a rematch with Marcos Maidana of Argentina.
"#Mayhem Mayweather vs. Maidana 2 September 13, 2014 MGM Grand in Las Vegas Live on Showtime PPV," five-division world champion Mayweather tweeted.
American Mayweather (pictured) improved his perfect professional record to 46-0 with a majority decision victory over Maidana to unify two world titles in their first fight in Las Vegas on May 4.
With that win, Mayweather added the hard-hitting Argentine's World Boxing Association belt to his own World Boxing Council title.
"Marcos Maidana is a tough customer and he gave me a fight that had me work for the victory," Mayweather said in a statement issued later.
"His style is difficult at best, but with experience comes a way and will to win. I'm not one to give second chances in the ring, but I want to give the fans what they want to see.
"I will be as prepared as I always am when I step in the ring on September 13. I only see the outcome one way and that's another successful night for me and my team."
Maidana made a fast start to their May 4 bout, launching a blizzard of punches and trapping his opponent against the ropes at every turn in the first few rounds.
Though Mayweather went on to dominate the second half of that contest, Maidana felt he had done enough to get the decision at the MGM Grand Garden Arena.
"I definitely feel like I won this fight. Floyd did not fight like a man, like I expected him to," Maidana (35-4, 31 KOs) said after the bout.
Mayweather exuded confidence while awaiting the decision, with one judge ruling the fight a 114-114 draw while the other two scored the bout 117-111 and 116-112 in his favour. "This was a tough, competitive fight, what the fans want to see," the American (46-0, 26 KOs) told a post-fight interviewer in the ring.
"Normally I go out there, I box, I move. Finally, I was in a tough, competitive fight. He's a tough competitor.
"If the fans want to see it again, we'll do it again."
Maidana expressed his delight after the September bout with Mayweather in Las Vegas was announced on Thursday.
"The rematch with Mayweather is the only fight that really motivates me," he said.
"I feel I earned it in the ring and Floyd owed it to me."
