UEFA Nations League: Saka Withdraws from England Squad
Bukayo Saka has left the England camp and returned to Arsenal for further evaluation of his injury.
The 23-year-old developed the problem during the Three Lions' 2-1 loss to Greece on Thursday.
Saka limped out early in the second half and was replaced by Noni Madueke.
He will no longer be part of England's 22-man team for Sunday's match against Finland in Helsinki.
Saka's injury is a blow to Gunners manager Mikel Arteta, who lost captain Martin Ødegaard to injury during the last international break.
In Ødegaard's absence, he has worn the armband and contributed 10 goals in all competitions this season.
