Former Penn State football coach Joe Paterno fractured his pelvis after falling at his home Saturday and was hospitalized, a source said Sunday.
Paterno, 84, was admitted to a Pennsylvania hospital Sunday morning and was in stable condition later in the day.
The fracture won't require surgery, but Paterno will remain hospitalized to undergo radiation and chemotherapy treatments for his previously diagnosed lung cancer.
"I have talked with him very recently and he is a determined fighter," the source said, speaking on condition of anonymity to protect the Paterno family's privacy.
"He is trying to reassure the people around him as to his condition."
Paterno, the university's head football coach for 46 years, previously fractured his pelvis when he was struck by one of his football players during a preseason practice in August.
Paterno was fired last month after a child sexual abuse scandal involving Paterno's defensive coordinator Jerry Sandusky rocked the Penn State campus. Sandusky faces 52 counts of child sexual abuse accusations for allegedly abusing 10 boys during a 15-year period. Sandusky maintains his innocence.
Paterno, who will turn 85 Dec. 21, is not the target of the investigation. However, Paterno had been told about a 2002 incident involving Sandusky and a boy in a Penn State locker room but did not report it to police. In firing him, school officials said the coach should have done more to prevent the alleged abuse.
