Following doctor’s orders, Phillip Phillips has canceled the remaining nine dates of his college tour. "His doctor said he has to get off the road," a source tells The Hollywood Reporter. "He was playing six shows a week, and it’s too much for him."
The American Idol season-11 winner's ongoing kidney issues -- he had surgery last year to remove massive kidney stones -- as well as a combination of exhaustion and dehydration have been slowing him down.
"His body doesn’t bounce back, and he's been feeling run-down," says the source.
