Former Zimbabwe captain Heath Streak is reportedly in a critical condition, according to media reports from the country.

Heath Streak, who stepped down as Bangladesh fast bowling coach in 2016, is suffering from cancer.

David Coltart, Zimbabwe's former minister of education, sport and culture, shared the news on Twitter and asked for his countrymen to pray for Streak's recovery.

"This is a call to prayer warriors in Zimbabwe and beyond. Heath Streak, one of the greatest cricketers our nation has ever produced, is extremely ill and needs our prayers. Please could we all be in prayer for him and his family," he posted.

Streak, who began his international career in 1993, played in 65 Tests and 189 ODIs with his last game coming in 2005. He also captained his side in 21 Tests and 68 ODIs.

"Heath has cancer and is undergoing treatment under one of the most respected Oncologists in South Africa. He remains in good spirits and will continue to fight this disease in a similar vein to that which his opponents faced during his revered days on the cricket field. The family hopes that you understand and respect their wish for this to remain a private family matter, and thank you for your prayers and good wishes. There will be no further official statements regarding his health at this time. Any news that becomes public should be regarded as rumour," said family spokesperson Joseph Rego.

"Heath has colon and liver cancer (Stage 4). All I know at this stage is Heath's immediate family was called to go to him in South Africa and I am not sure on any details thereof. I did message Heath and he did respond but I'm sure at this stage the family will want privacy. It sounds like the cancer is spreading pretty quick cause last week he was fishing," said former player and close friend Sean Williams to Cricbuzz.
