Australian golfer Jarrod Lyle has reportedly been struck down by leukaemia for a second time.

The 30-year-old was diagnosed with acute myeloid leukaemia as a 17-year-old but overcame nine months of bed rest and chemotherapy treatments to become a professional golfer on the US PGA Tour.

Lyle flew back to Australia last week for the birth of his first child, now due to be induced on Friday after the health revelations.

Close friend and fellow Australian golfer Robert Allenby, who befriended Lyle during his first stint with cancer, tweeted the news.

“My heart goes out to my mate, great golfer Jarrod Lyle. New baby coming tomorrow & big fight at cancer again.”
