Manchester City defender John Stones was substituted early in England's friendly match against Belgium due to a suspected adductor injury. The injury adds to a growing list of concerns for both England manager Gareth Southgate and City boss Pep Guardiola, who are counting on Stones for the upcoming European Championship and City's final month of the season. Stones' injury comes just days after his teammate Kyle Walker also suffered a hamstring injury, leaving both players uncertain for upcoming matches.
