 Ali turns 64 in January |
Former world heavyweight champion Muhammad Ali is in good health despite reports questioning his condition. Newspapers on Friday quoted an unnamed family friend as saying that Ali, who suffers from Parkinson's Disease, "may only have months to live."
But Ali's marketing agent Harlan Werner told BBC Sport: "Muhammad is fine and he has numerous appearances lined up.
"He had surgery on his back and was in therapy for that, but that had nothing to do with Parkinson's. He is fine."
Ali won the world heavyweight title three times in a brilliant career that saw him lauded as "the greatest".
Werner said: "It is disrespectful to Muhammad to suggest that he would not tell the truth about his health.
"Of all the people in the public eye, Muhammad Ali has always told the truth."
Ali was named Sportsman of the Century by BBC television viewers in 1999 and received a similar award from US magazine Sports Illustrated.
