"There's a very small fracture in there," said the left-handed batsman. "I'll miss the game tomorrow unfortunately but, as regards the first game of the tournament, I should be good to go," he added, referring to England's match against South Africa at The Oval on Thursday.
Joe Root was not with the England side on Friday because of personal reasons but is set to play against Australia. Leg-spinner Adil Rashid is likely to sit out the game as he manages a shoulder issue.
