Virender Sehwag could be a doubt for the Champions League T20 after he strained a ligament in his left ankle during India’s final Super Eights match in the World Twenty20 against South Africa in Colombo.Sehwag went off the field during South Africa’s innings and did not return. It was reported that he would need two weeks of rest. Sehwag had given up the Delhi Daredevils captaincy for the Champions League, which begins on October 9, but remained a key member of their squad. Delhi are scheduled to open their campaign on October 13 in Centurion.Sehwag had a poor World Twenty20 in Sri Lanka, scoring only 54 runs in three innings at a strike rate of 112 and was left out of the group game against England. India failed to qualify for the semi-finals despite winning four out of five matches, exiting the Super Eights on net run-rate.
