Four belts, two undefeated fan favorites— and a title fight simply billed as "The One." #THEONE takeover has begun. Mayweather vs. Canelo is set to be the biggest boxing match in the last decade, and the fighters have kicked off an 11-city tour to officially announce and promote their title fight set to take place at the MGM Grand in Las Vegas on Sept. 14, 2013.

The Tour began at NYC's Times Square in front of thousands of people. Check out the video above.

Mayweather, 36, is unbeaten in 44 fights with the last a unanimous 12-round decision over Robert Guerrero on May 4 in defense of his 147-pound title. "The Earth is my turf," Mayweather said to the crowd before continuing, "You can put me in any ring and I will always come out victorious." Alvarez, a 22-year-old star from Mexico, is 42-0-1 and unified the 154-pound titles in April with a unanimous victory over Austin Trout on April 20 had this to say, "In the sport of boxing, it's everybody's time, and this is my time."

There can only be ONE champion, only ONE fighter will remain undefeated, who will be #THEONE?
