Stand-in Bangladesh captain Shakib Al Hasan is set to find out next week if he must undergo surgery to solve a groin problem.
The world's top all-rounder in one-day cricket is flying to Australia for medical treatment and advice on the best way to proceed.
His trip to Australia comes after he has been playing on through the pain for the past month.
Bangladesh Cricket Board spokesman Rabeed Imam said: "He has been in acute groin pain during the past one month and had to play with painkillers.
"He will fly to Australia next week where doctors will see his injury and decide whether to operate on him."
The left-arm spinner is the world's fourth-ranked Test all-rounder and has been labelled as the best Bangladeshi player since the country won Test status in 2000.
Growing in maturity, he stood in for injured Bangladeshi captain Mashrafe Mortaza in July and led the side to a Test and one-day international clean-sweep against the West Indies.
The 22-year-old also led the country to a 4-1 one-day series triumph away against Zimbabwe this month.
He joins a long list of Bangladeshi players who have been sidelined by injuries since July.
Captain Mashrafe underwent surgery on both knees earlier this month in Australia, while left-arm spinner Abdur Razzak and young pacemen Rubel Hossain and Nazmul Hossain were injured during the team's tours of the West Indies and Zimbabwe.
