The Arsenal midfielder is set to start for England in their friendly with Brazil at Wembley on Wednesday night but manager Hodgson hopes there is not too much expectation placed on him so early in his career.
"Jack is a player who carries a huge weight of responsibility at a young age," he said.
"I hope everyone is going to understand he is still a young man, he is 21 and still capable of playing in the under-21s, not that he will.
"I'm anxious in some ways and, while delighted with his form and the way he plays and sharing everyone's enthusiasm about his quality, I want to play it down a bit too.
"I wouldn't like to see him have to take a backward step because all of a sudden his name is being put forward as the saviour of the English football team. We've got other players too.
"I'm hoping Jack's contribution, which will be a big contribution, will be matched by big contributions by the other players like (Wayne) Rooney, (Steven) Gerrard, (Frank) Lampard, (Ashley) Cole, (Glen) Johnson etc."
