Danny Welbeck and Glen Johnson both sat out of England's training session on Wednesday as a precaution.
Manager Roy Hodgson took charge of the squad for the first time at the Etihad Stadium ahead of Saturday's friendly against Norway in Oslo.
Welbeck and Johnson are not thought to be injury doubts for the weekend.
England will take on Norway and Belgium in friendly matches before their first Euro 2012 group game against France on Monday, June 11.
