England duo Sol Campbell and Wayne Bridge sat out the squad's final training session in Sardinia. They were suffering from sore feet and were rested as a precaution, but all the others took part before catching a flight back to England.
Chelsea defender Bridge and Arsenal's Campbell are expected to train when the squad resumes preparations in Manchester on Monday.
Darius Vassell, who had a hamstring strain, has returned to full training.
Vassell was the one injury doubt in Eriksson's 23-man squad.
Four Manchester United players - Nicky Butt, Paul Scholes, Gary Neville and Phil Neville - as well as David Beckham and Owen Hargreaves, all had an extra week's training with their clubs.
Tottenham striker Jermain Defoe, who is with the squad on stand-by, faces the heartbreak of returning home if Vassell stays fit.
Eriksson said: "He knows that and so do the 23 players. They know it is not a competition if he shall be in or out.
"He comes in if we have a problem. I didn't want the other 23 to be competing until the tournament starts.
"We don't have any big problems. I think Vassell will make it, but we've two games to go."
Eriksson can make changes to his provisional squad until 2 June, following the initial warm-up game against Japan, but must then confirm his final 23-man party to Uefa.
