Injured senior speedster Ishant Sharma and off-spinner Ravichandran Ashwin will undergo a fitness test on Saturday before the selectors take a final call on their availability for the upcoming two-Test series against the West Indies starting at Rajkot on October 4.

"Ashwin is already doing his rehabilitation at the NCA for groin injury. Even Ishant is expected to join him there. As of now, there is a fitness test scheduled on Saturday, September 29. The selectors may announce the team a day earlier if NCA physios and trainers rule the duo out even before fitness tests," a senior BCCI official told PTI on Wednesday.
