Guerrero backing cause dear to his heart

LAS VEGAS -- When Robert Guerrero enters the ring to face Floyd Mayweather Jr. at the MGM Grand on Saturday night, his trunks will bear the logo of an organization called Be The Match, a nonprofit entity that runs the national registry of potential bone marrow donors.

It is, of course, a cause dear to his heart, given that his wife Casey was diagnosed with leukemia in 2007 and relapsed three times before finding a matching marrow donor. She underwent a successful transplant in 2010 and has since been declared cancer-free.

"My wife was fortunate to find a marrow donor," Guerrero said. "But there are thousands of other blood cancer patients out there who still need a match. So I'm spreading the word: Go to BeTheMatch.org and join the Be The Match registry. You could be someone's cure."
