DALLAS — Former Penn State football coach Joe Paterno's health is improving during his battle with lung cancer and recovery from a broken pelvis, says his son Jay Paterno.

"His spirits are really good," the younger Paterno said Friday. "He's a fighter. You know what his character is and what his makeup is. He fights. He never gets down. It's about the next challenge, and this is another challenge for him."

Joe Paterno was fired four days after former assistant coach Jerry Sandusky was indicted on charges of sexual abuse, a case that now involves 10 boys. Paterno was told of one alleged on-campus assault in 2002 by then-graduate assistant coach Mike McQueary, now a full-time member of the staff who is on administrative leave.

Jay Paterno indicated that his father would be exonerated once "everything comes out, and once everybody sees everything that's happened."
