England manager Roy Hodgson has said that no risk was taken on Fabian Delph's fitness after the midfielder suffered a hamstring injury on Tuesday night.
Delph sustained the problem just nine seconds into England's 2-0 win over Switzerland and was replaced by Ross Barkley in the second minute.
The 25-year-old, who signed for City from Aston Villa in the summer, had only recently recovered from a hamstring injury he picked up during preseason.
Hodgson said: "He pulled his hamstring. No, [Delph was] not [a concern] at all. He's trained every session, felt good, played in San Marino.
"It was just that burst, that acceleration. He felt it's a definite pull. How serious, a scan will have to show us.
"We're very disappointed, as is he. It's not something that we could have prevented because there was no risk putting him on the field.
"I can't remember having to make a change before after nine seconds. It robbed us of one early on. It gave us a chance to play Ross Barkley, who had been unlucky to lose his place."
