Buttler, who has been backed to continue as England’s white-ball captain by managing director Rob Key, took a short break from the game after the T20 World Cup and is understood to have sustained the injury while preparing for the Hundred. An initial scan was inconclusive, raising hopes he would be available towards the end of the competition, but his withdrawal was confirmed on Saturday.
Buttler has suffered several calf injuries in recent years, including a strain two years ago which ruled him out of England’s seven T20Is in Pakistan and briefly threatened his participation in the T20 World Cup 2022.
