Goalkeeper Joe Hart has revealed John Terry took part in England's first full training session after arriving at their base in Krakow, Poland.
The Chelsea central defender was among those who needed to be checked after suffering a tight hamstring in Saturday's friendly win over Belgium at Wembley.
And, after losing four players to injury already, Hart admitted manager Roy Hodgson will be relieved not to suffer any more setbacks.
Asked whether Terry played a full part in training, Hart told Sky Sports News: "Yeah, he was fine. Flying around like he usually does. He didn't seem to be holding back."
And England's No.1 revealed Scott Parker also took part in training, despite concerns over the Achilles tendon injury which kept him out of Tottenham's Premier League run-in.
"You read and hear about Scott Parker and you have to actually ask him 'is anything wrong with you' and he's like 'no, not really', so it's interesting to listen to when you actually speak to the guy, he is absolutely fine."
Hart believes his Manchester City team-mate Joleon Lescott has a real chance of starting for England's opening group game against France alongside Terry in the heart of defence at the Donbass Arena in Donetsk on Monday.
He continued: "I thought Joleon played outstanding (against Belgium). I thought he worked really well with John Terry.
"Obviously John came off in that game with a bit to go and Jags (Phil Jagielka) came on and did great as well. There's plenty of depth in the squad.
"The partnership between Joleon and Terry worked straight away. Obviously JT prefers to play that left side, but being right-footed and playing on that left-hand side is a little bit different.
"But, I'm pretty sure he's played on that right-hand side before and done brilliantly and I'm sure Joleon will fit in nicely on that left-hand side with JT."
Hart also said the squad has been very impressed with the training facilities at their base in Poland.
The Three Lions are holding their training sessions at the Hutnik Municipality Stadium and the City keeper could not talk highly enough of the facilities.
"It was great, really impressed. It's not too far and it's an interesting journey and the pitch is perfect and that's all that we really need to worry about," said the 25-year-old.
"The pitch is great for us. Everything that we need is there for us. There's room for massages and strappings and for whatever is required, it's all there."
England striker Jermain Defoe has returned home following the death of his father.
The Football Association confirmed that the player is expected to return at some point and no replacement is being called up.
Hart said: "We'll be ready for him when he wants to return."
