Ok, boxing fans can breathe again. The highly anticipated return of Floyd Mayweather to the ring is back on.

After the bout between him and Juan Manuel Marquez was postponed a week ago, after Mayweather suffered a rib injury, both fighters agreed to a rescheduled date of September 19 when he received clearance from his doctor to participate on the new date.

Mayweather vs. Marquez: "Number One/Numero Uno," which will still take place at MGM Grand in Las Vegas and be televised live on HBO Pay-Per-View, will now take place on what is historically considered boxing's biggest weekend, and falling on the time-honored tradition of Mexican Independence Day.

"I am relieved to be cleared to fight as I was already looking forward to getting back in the ring," said Mayweather in a statement. "Trust me, September 19 is a great weekend for boxing, and all of my fans, of which there are many Mexicans too, can certainly hold on to their hats and sombreros when I get back in to the ring and show them what they have been missing these past 18 months. I will destroy Marquez and reclaim my rightful place as boxing's pound-for-pound king all in one night. Don't miss it."

Marquez, who has also agreed to fight on the new date, is excited about appearing yet again on the time-honored tradition of El Grito de Independence.

"I am happy that Mayweather has been cleared to fight and we can get down to business on September 19," adds Marquez. "This weekend is not just an important weekend for boxing, but even more so for all of the Mexican and Mexican-American people I will be fighting for who will have a great reason to celebrate my win over Mayweather, which will be for all of the people and for the entire country of Mexico that night. I am sure of victory and si se puede- yes we can and yes we will!"
