England have announced that John Stones has withdrawn from the squad ahead of Tuesday's friendly with Ivory Coast at Wembley.
The centre-back was due to start in Saturday's 2-1 win over Switzerland but had to be replaced at the last minute by Ben White after complaining of tightness in the warm-up.
Gareth Southgate did not rule Stones out of contention for the Ivory Coast clash after the weekend's win, but the 27-year-old has now returned to Manchester City as a precaution.
An update on englandfootball.com read: "John Stones has left the England camp and returned to Manchester City. Having withdrawn from the starting lineup ahead of Saturday's 2-1 victory against Switzerland at Wembley, the defender has continued to be assessed.
"After today's session at Tottenham Hotspur's training ground, it was decided that Stones would play no part against Cote d'Ivoire on Tuesday and has returned to his club as a precaution."
Stones has featured 20 times for Man City in all competitions this season - playing the full 90 minutes in his side's last three Premier League games amid Ruben Dias's hamstring injury.
