American George Foreman, one of the great second acts in sports who reclaimed the heavyweight boxing title after coming out of retirement and became a celebrated product pitchman, died on Friday at age 76, his family said, according to an agency report.

“A humanitarian, an Olympian, and two time heavyweight champion of the world, He was deeply respected – a force for good, a man of discipline, conviction, and a protector of his legacy, fighting tirelessly to preserve his good name – for his family,” the family said, describing Foreman in a post on Instagram.
