Mayweather donates $100 000

Las Vegas - Boxer Floyd Mayweather Jr. has made good on a promise to a Nevada judge to donate $100 000 to a breast cancer support organization.

The undefeated fighter gave the money on Wednesday to officials from the Susan G. Komen for the Cure research and support foundation. The presentation was made during a news event at his gym in Las Vegas.

Foundation executive Stephanie Kirby says the donation will go a long way at the Las Vegas nonprofit, which operates with about a $1 million annual budget.

Mayweather's lawyers promised the judge who sentenced Mayweather in December in a domestic battery case that the boxer would make the donation. Mayweather is due to serve a 90-day jail sentence in the case beginning June 1.
