Defender Ben White (25) has left the England camp and gone home for personal reasons, the FA said in a statement on Wednesday, adding that he was not expected to return to the tournament.
White, normally a central defender but who has been operating as right back for Premier League table-topping Arsenal this season, was something of a surprise inclusion in the squad.
He missed training two days ago, with the FA saying he was ill.
White, who has four caps, was called up as a late replacement for last year's European Championship but did not feature.
