Press Release: Boxing's king of the ring Floyd Mayweather will participate in tonight's NBA All-Star Celebrity Basketball game (ESPN HD at 7:00pm), as part of his participation in this weekend's NBA All-Star Game activities in New Orleans.  Mayweather, who is taking a break from his boxing career, is having the time of his life and enjoying himself as he literally drives himself across the country in his own whistle-stop tour that has already included stops in Arizona, Texas, Illinois, Michigan, Ohio, New York, Kentucky, Tennessee, Georgia, Mississippi, and Louisiana.  "This is the first real break I have taken in my entire career," said the pound-for-pound champion.  "It feels great to stop, make appearances, talk to kids and at the same time enjoy my time off.  If you think I was good before, wait until I come back from this."
