Interacting with media persons at Rajkot, Kumble said,"Bit disappointed with some injuries; it's unfortunate. Feel sad for Rohit (Sharma) because he was doing well."
Rohit sustained an injury on his right upper quadriceps tendon, during the fifth and final match of the five match one-day series against New Zealand in Vizag on October 29.
Rohit is likely to be out of action for a minimum of 12 week, effectively ruling him out of the four-Test rubber against Australia early next year.
BCCI medical team on Friday (Nov 4) confirmed that the Mumbai batsman might undergo surgery after consulting a specialist in London next week.
"He (Rohit) will travel to London early next week for specialist consultation with a possibility to undergo surgery, as a result of which, he is expected to miss at least 10 to 12 weeks of cricket," a BCCI media realease informed.
"The BCCI medical team will extend all support to Rohit Sharma, to regain full fitness and further contribute to Indian Cricket," added the release.
Kumble is facing a selection conundrum as he needs to choose either "fifth bowler" Hardik Pandya or "sixth batsman" Karun Nair for the series-opener against England but India's chief coach did not reveal much on his preference, praising talent of both the players.
