England manager Roy Hodgson has insisted that no risk was taken with midfielder Fabian Delph after he suffered a hamstring injury in the Euro 2016 qualifier against Switzerland on Tuesday evening.
The Manchester City man sustained the problem just nine seconds into England's 2-0 victory at Wembley and was replaced by Ross Barkley.
Delph had recently returned from a hamstring injury that he picked up during pre-season, but Hodgson has said that his early exit caught him by surprise.
When asked about the 25-year-old's fitness, Hodgson told ESPN: "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."
Delph is expected to miss City's Premier League clash at Crystal Palace this Saturday.
