Striker Jermain Defoe rejoined the England squad in Poland on Saturday morning and immediately headed out to training with his team-mates.
The Spurs forward had returned home following the death of his father earlier in the week but was back at the team's hotel in Krakow.
Less than half-an-hour after arriving at the hotel, Defoe climbed aboard the bus with his 22 fellow squad members to head off to training.
The news will boost manager Roy Hodgson, who has several injury worries to contend with ahead of their Euro 2012 Group D opener against France on Monday.
Defender Joleon Lescott is reportedly nursing groin and knee problems, while John Terry and Ashley Cole are said to be carrying knocks.
There was also brief concern over James Milner, who has been heavily tipped to start on Monday, after the City midfielder did not take part in England's visit to Auschwitz and the Oskar Schindler factory on Friday.
But the Football Association soon confirmed the 26-year-old was advised to stay off his feet for the afternoon after suffering blisters and were confident he would train on Saturday.
Milner was one of nine players not to take part in full training on Friday 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 and were part of the individual players' rehabilitation programmes.
