Guerrero gives up IBF belt to be with ill wife
GILROY: Robert Guerrero has vacated his International Boxing Federation super featherweight title to be with his wife, Casey, as she battles leukemia.
Guerrero announced his decision on Tuesday, a week after he was forced to drop out of a proposed bout with Michael Katsidis.
Casey Guerrero is in hospital as she recovers from a bone marrow transplant and chemotherapy.
Guerrero, who owns a record of 25-1-1 with 17 knockouts, won a featherweight title before his wife was diagnosed with the disease in 2007.
He vacated that title in 2008 to move up to super featherweight, and claimed the IBF title last August with a 12-round unanimous decision over South African Malcolm Klassen in Houston.
The Guerreros, whose hometown is just south of the San Francisco Bay Area, have two small children.
