Neville picked up the knock whilst playing for England in their 2-1 win over Poland on last week's World Cup qualifier in Chorzow.

The injury comes as a blow to Sven-Goran Eriksson with two more important qualification matches coming up next month.

Neville has won 70 caps for England but limped off after a first half challenge in the game on Wednesday and is now a doubt for the games against Wales on 09 October and Azerbaijan four days later.
