The 25-year-old prop, who is one of those likely to make Frances 2007 World Cup squad, was called up to play for Les Bleus during the Tests against Romania at the start of June.

During the team meeting in Marcoussis, he was diagnosed with a throat infection for which he received three injections, allowing him to play in France's thrashing of Romania.

On returning to Castres following France's victory over South Africa, Attoub complained about his back for which he received further treatment.

But his medical condition worsened at the start of July and examinations revealed he had caught a bacterial infection known as staphylococcus aureus.

''My spine was full of germs,'' explained Attoub, who has been hospitalised since July 20, to L'Equipe.

''But I don't know who gave it to me, the most important thing is to regain my health and then to be able to play rugby again.

''I am sure I will be back, an experience like this one can only make you stronger.''

France will gather again this autumn for Tests against Argentina and New Zealand.
