Sven-Goran Eriksson expects Gary Neville to be fit for England's friendly against Jamaica on Saturday.
Neville, 31, came off at half-time against Hungary yesterday with a slight hamstring problem.
Eriksson insisted the move was 'more caution than injury' and is optimistic Neville will win his 80th cap against Jamaica at Old Trafford.
The players who appeared against Hungary were involved in a light training session today in the gym with England's physio team.
Those who did not feature in the 3-1 win were put through a more rigorous work-out.
Neville, who missed the last World Cup through injury, is hugely important to Eriksson's team because of his defensive solidity and his vast experience.
He is the only specialist right-back in the squad and the England boss will not gamble with his fitness if he feels the hamstring tighten before Saturday.
Eriksson said: ``It's important we don't take any risks with Gary Neville because we need him and we need him very much.''
Jamie Carragher switched from midfield to right-back when Neville went off against the Hungarians. Owen Hargreaves is also capable of playing there.
Luke Young, who deputised for Neville when he was injured earlier this season, was on stand-by for the World Cup but was forced to pull out with an ankle injury.
He was replaced by Michael Dawson, who is an orthodox central defender.
