Former UCLA basketball coach John Wooden, whose teams won 10 national titles, was in grave condition Thursday, school sources confirmed.
Wooden, 99, is being treated at UCLA Medical Center, according to the sources who were not authorized to speak publicly. A UCLA athletic department official declined to comment on the situation.
Wooden's health has been an issue in recent weeks and he was briefly hospitalized about a month ago, a school source said.
Wooden won 620 games during his coaching career, which began at UCLA in 1948. He retired following the 1974-75 season, after his Bruins won their 10th title in 12 seasons. His "Pyramid of Success" is used as a teaching foundation in business and for coaches across the country, in every sport.
