Joe DiMaggio had another "serious setback" on Monday in his slow recovery from lung cancer surgery -- an infection that the doctors already thought they had brought under control. The 84-year-old Hall of Famer developed the lung infection on Friday, but after a weekend of intensive treatment in a Florida hospital, his temperature and white blood cell count were back to normal Monday morning, said Dr. Earl Barron. "We have every hope that he will survive, but anything can happen," Barron told the Associated Press. "Considering his age, it's going to be a long road back for him."
