Boxer vacates title to help wife fight cancer

Robert Guerrero of the United States has vacated his IBF junior

lightweight title to be with his wife, Casey, during the latest

steps in her lengthy struggle with leukemia.

Guerrero announced his decision Tuesday, a week after he was

forced to drop out of a prospective fight with Australia’s Michael

Katsidis.

Casey Guerrero is hospitalized while recovering from a bone

marrow transplant and chemotherapy.

Guerrero (25-1-1, 17 KOs) won a featherweight title before

his wife was diagnosed with the disease in 2007. He vacated that

title in 2008 and moved up to junior lightweight, dominating

Malcolm Klassen last year to claim the IBF belt.

The Guerreros have two young children.
