The McLaren tester ended last Friday in the medical centre after, in a high speed bend, writing off not only his MP4-20, but the circuit barrier he struck.
Wurz, 31, was 'given the all clear,' the Woking based team said.
"I am OK and feeling fine," the Austrian reported, "just disappointed I couldn't continue."
It is reported that Michelin is investigating what is thought to have been rear tyre failure.
"We all had to return to the short track layout," said disappointed Sauber engineer Giampaolo Dall'Ara, also ruing Jacques Villeneuve's run-in with a kerb that ended his day.
Also in France were Renault, Toyota, Red Bull and BAR, whose Takuma Sato went quickest.
Elsewhere, Ferrari's Luca Badoer tested at Fiorano on Friday and Saturday, but when Rubens Barrichello arrived, so too did the rain, ending the run.
