James Milner sat out England's visit to Auschwitz and the Oskar Schindler factory on Friday after suffering blisters.
The Football Association confirmed the Manchester City midfielder was advised to stay off his feet but were confident he would train on Saturday.
Apart from Jermain Defoe, who returned home on Thursday following the death of his father, Milner was the only member of the England squad not to visit either Auschwitz or Schindler's factory.
The 26-year-old is also the only member of the squad to have played every minute of manager Roy Hodgson's first two games in charge and has been heavily tipped to start Monday's Euro 2012 Group D opener against France.
Milner was one of nine players not to take part in full training this morning, eight of whom are expected to play on Monday.
The FA were at pains to stress all the absences were planned after a tough session behind closed doors on Thursday and were part of the individual players' rehabilitation programmes.
