Arizona Cardinals head coach Bruce Arians had a "small portion" of his kidney removed in February after tests revealed a cancerous spot on the organ.
According to Arizona's website, Arians revealed the medical scare in his new book – "The Quarterback Whisperer" – which was released on Tuesday.
Arians learned of the diagnosis of renal cell carcinoma in December when his doctor noticed a spot on an ultrasound taken during an examination of a hernia.
The 64-year-old coach opted to wait until after the NFL season to have it removed.
"Now I feel great," Arians wrote. "My energy has returned. I'm told I'm cancer-free again.
"I'm ready for at least one more season of NFL football — maybe more."
Arians was hospitalised twice last year — once during the preseason for diverticulitis and again following a game at the Vikings due to chest pains on November 20.
