Leeds United have included star youngster Sam Byram in their squad which has headed off for Slovenia today.
The players are set to be put through their paces on a 10-day camp that will include three games.
The travelling party has included right-back Byram, who is recovering from a hip injury that ruled him out of England’s under-20 squad recently.
Goalkeeper Jamie Ashdown has also made the trip after being an injury doubt.
But striker El Hadji Diouf has not travelled as he is being treated for a shin infection and winger Ryan Hall is also missing as he expects to be a father this week.
The remainder of the senior squad have all made the trip along with young professionals Ross Killock, Charlie Taylor and Alex Cairns.
The opening game of the trip is against a Slovenian representative side on Wednesday.
