John Stones has pulled out of the England squad and returned to Manchester City, the FA has announced.
The City centre-back was initially named in Gareth Southgate's starting XI as the Three Lions took on Switzerland in a friendly on Saturday, however, he was withdrawn from the team moments before the match got underway at Wembley. Arsenal's Ben White replaced him in the 2-1 victory.
After the match, Southgate appeared optimistic that the yet unspecified problem wouldn't keep Stones out of action for long and was hopeful he would be available for final match of the international break against the Ivory Coast on Tuesday. He said: "He felt something in the warm-up. We don't think it's too serious. It's possible he could be okay for Tuesday, but we didn't have time to assess it properly before the game, so we didn't want to take any chance."
