The Frenchman, who underwent surgery for a second time on his right knee at the end of March, had targeted last weekend's World Cup event in Val d'Isere to make his long-awaited comeback.
But he skipped the race in his home country, saying he did not feel 100 per cent ready.
Instead, he will feature at Pozzo di Fassa in the Dolomites.
His expected return to World Cup action is now scheduled for December 18 at Madonna di Campiglio.
In Grange's continued absence, his team-mate Alexis Pinturault won the slalom in Val d'Isere on Saturday.
