John Stones will miss Premier League leaders Manchester City's trip to his former club Everton this weekend.
The England defender will sit out after suffering a head injury in Tuesday's international friendly against Italy at Wembley.
The 23-year-old has now recovered from the blow, but will not be available on Saturday evening due to concussion protocols.
Manager Pep Guardiola said: "John Stones - a concussion in the last game of the international break. He feels really good but the rule is seven days off, so that's why he's not available."
Top scorer Sergio Aguero is also unlikely to be involved at Goodison Park as City look to claim a victory that would then enable them to secure the title against rivals Manchester United next week.
