Saints defender Luke Shaw is a doubt for England's World Cup warm-up match against Peru tomorrow night, at Wembley.
The game will be the last on domestic soil for Roy Hodgson's squad before they jet off to a Miami camp, from which they will then fly to Brazil.
Hodgson said: "'We have no injury concerns, although unfortunately, yesterday, Luke Shaw developed a slight cold.
''We are very cautious, so he travelled down separately and didn't train today.
''I couldn't tell you at this moment in time if he will recover for tomorrow, but it is a very minor issue that will quickly go over.
''Whether it will go over in time for him to take part tomorrow, I won't know until tomorrow morning.''
