England captain Harry Kane is set to have a scan on his right ankle on Wednesday, before Friday’s World Cup group match against the United States.
Kane sustained a blow early in the second half during the 6-2 victory over Iran in Group B on Monday.
He was eventually replaced by Callum Wilson and was later seen with light strapping on the ankle.
The 29-year-old Tottenham striker has scored 51 goals in 76 appearances for England.
Manager Gareth Southgate will hope Kane’s scan results are positive as he prepares his team for the second game of the group stage.
Midfielder James Maddison missed the Iran match as he recovers from a knee issue, while defender Harry Maguire came off feeling ill on Monday.
Wilson did not train in a light session with the rest of the substitutes at England’s Al Wakrah training base on Wednesday, but is not considered a fitness doubt.
