Head coach Fabio Capello will take no risks with Ledley King after Tottenham Hotspur questioned the wisdom of calling the defender into the England squad.
King was a surprise inclusion in the squad to face Slovakia and Ukraine as the Spurs captain suffers with a chronic knee condition which normally prevents him from playing in consecutive games.
The central defender has not been called up since 2007 and his inclusion in the 23-man squad has concerned Spurs boss Harry Redknapp.
However, the FA have promised to take no risks with the fragile 28-year-old.
"The England management have spoken to Tottenham Hotspur today and explained that they will take no risks at all with Ledley King," said an FA spokesman.
"They fully understand the player's injury situation but they wanted to have a close look at him in the team environment as Ledley has not previously been part of a Fabio Capello squad.
"He will be monitored during the week by the England and Tottenham Hotspur medical staff before any decision on training or playing is made."
Earlier in the week, Redknapp had revealed his concern about King joining up with the England squad.
"They're taking him away from people who know how to look after him and that's a problem," he warned.
"The international break was an important time for his condition to settle down.
"If he plays against Slovakia on Saturday, he won't be able to play against Ukraine on Wednesday because his knee will swell up again.
"If he doesn't play on Saturday but plays against Ukraine on Wednesday he won't be able to play for Tottenham at Blackburn on Saturday lunchtime - no chance."
