England captain Harry Kane was able to train with his team-mates on Wednesday, boosting hopes he will be fit for Friday's World Cup group match against the United States.
Tottenham striker Kane sustained a blow early in the second half during the 6-2 victory over Iran in Group B on Monday.
He was due to have a scan to assess the damage on Wednesday, but England goalkeeper Jordan Pickford said the striker is "fine".
"I think he is good," said Pickford.
"I'm sure he is fine. He was out on the grass with us today which is good. He is our captain."
