The megabout most fight fans have been craving for quite sometime might finally come to fruition, as Floyd Mayweather has gone public with a possible May 5 bout with Filipino icon Manny Pacquiao.

The two pound-for-pound boxing stars have had a long-running feud, and with Mayweather scheduled for a 90-day jail sentence in June for domestic violence, the window might be closing for the welterweights to finally meet in the ring.

Mayweather posted on Twitter: "Manny Pacquiao I'm calling you out, let's fight May 5th and give the world what they want to see." He also added another post: "My jail sentence was pushed back because the date was locked in. Step up punk."

Mayweather's comments follow a Pacquiao interview where he stated that he wanted to fight Mayweather next.

"I've said this over and over before and I'm saying this again, I want Floyd Mayweather Jr. to be my next opponent and I haven't changed my choice despite recent developments," Pacquiao told PhilBoxing.com.

With Mayweather having already booked the MGM Grand in Las Vegas as his venue, it seems that the location has been set. However, Pacquiao's promoter, Bob Arum, has said he wants a larger capacity site, such as Cowboys Stadium in Arlington, Texas.

Both Mayweather and Pacquiao won their last fights, but in rather controversial fashion.

In September, Mayweather defeated Victor Ortiz in a bizarre knockout. After a stoppage in action in the fourth round, Mayweather threw two power punches at Ortiz immediately following referee Joe Cortez's restart, which dropped Ortiz. Mayweather's reaction came after Ortiz had lunged at him with a headbutt moments earlier.

Less than two months later, Pacquiao earned a majority-decision win over Juan Manuel Marquez, in a hotly contested bout. Pacquiao was the heavy favorite, but Marquez put on an impressive showing, and many felt that Marquez deserved the victory.

Whether a bout between the two superstar prize fighters finally materializes remains to be seen. There have been discussions of a Mayweather-Pacquiao fight since 2009.
