Milner, Baines miss training
James Milner and Leighton Baines were the only absentees from England training on Tuesday ahead of the friendly with Peru.
Milner missed the session at St George's Park in Burton with a cold and Baines was allowed to leave the squad briefly to deal with a family matter.
The Everton left-back is expected to re-join his team-mates on Tuesday evening.
England's main injury worries, including Manchester United duo Wayne Rooney and Phil Jones, were able to take part in training along with Arsenal's Jack Wilshere and Alex Oxlade-Chamberlain.
Jones injured his shoulder towards the end of the Premier League season and Rooney missed the run-in with a groin problem - Jones did not take part in any of the full-contact training.
Those heading for Brazil were joined by standby players John Stones of Everton and Liverpool's Jon Flanagan.
England face Peru at Wembley on Friday night in their final friendly before crossing the Atlantic.
They then face Ecuador on June 4 and Honduras on June 7 - both games in Miami - before jetting down to Brazil for the start of the tournament on June 12.
