Manchester City winger Shaun Wright-Phillips is a major doubt for England's friendly with Slovakia on Saturday after missing training for the fourth successive day.
Wright-Phillips has not taken part in any of the training sessions at the squad's Hertfordshire base as he is struggling with an ankle injury.
However, he could yet feature in next Wednesday's World Cup qualifier against Ukraine at Wembley.
Elsewhere, head coach Fabio Capello has been boosted by the return to action of striker Peter Crouch.
The Portsmouth frontman arrived for international duty with a minor calf strain picked up in last weekend's Premier League victory over Everton.
But after missing training in the early part of the week, Crouch took a full part in Friday morning's session.
Meanwhile, David Beckham has spoken of his pride at being on the cusp of becoming England's most capped outfield player.
The former captain, who is currently on 108 caps, will break Bobby Moore's record should he play against either Slovakia or Ukraine.
"This is one of the biggest highlights of my career to still be in this team at almost 34. To be on 108 caps is something special for me," said Beckham.
"Every time I meet up with England it is a huge honour. To be on that amount of games is a big honour for me and every time I play it is a bonus.
"Being on 95 caps, I never expected to make 100. When I did that, people expected me to retire then. To be on 108 and hopefully get to 109, I am happy with that."
