New Delhi:Having aggravated a recurring ankle injury, Indian striker Sunil Chettri is in doubt for the Nehru Cup football tournament starting here on August 19.
Chettri's right ankle injury flared up during the month-long training trip to Barcelona.
"Nothing is final yet and we have to decide on him. But his ankle injury has flared up," team sources said.
The recurring injury didn't allow him play first two of the four matches against Spanish third division sides during the Barcelona.
The star striker took the field for just 45 minutes in the third match and played for 58 minutes in the fourth and final match.
He was largely restricted to doing light training during the trip.
