As was the fear when Robert Guerrero pulled out of his March 27 fight with Michael Katsidis, ESPN.com's Dan Rafael reports that Guerrero's wife, Casey, is indeed battling leukemia again. Casey recently underwent a bone marrow transplant: "They won't really know if the bone marrow is going to take, so we're hoping that it does," [co-manager Bob] Santos said. "Robert wanted to fight. He thought he could spend half the day with her and train the other half the day, but she started to take a turn for the worse. I told him point blank there is no way I would allow him to fight. Me and Shelly had to talk him out of it. This is a tough sport and if he's going to fight somebody like Katsidis you have to be 100 percent focused. With this situation, how could he be?" We at Bad Left Hook send our best wishes and prayers out to Casey and Robert Guerrero.
