This season Jones has been injured on five different occasions, with these including foot, pelvis, knee and hip problems plus concussion, though he has still managed 30 appearances for United - including in the Community Shield - and two more for England.
Moyes said: "I think that is how he plays. He is an old-fashioned player who throws himself about and you may say: 'Why did you do that?' But that is why he has had a few injuries and been caught out a few times. We certainly don't want that to continue. We think that, with maturity, he will recognise when he should go for it and when he should stand up."
