Thuram's absence is due to ongoing issues with patellofemoral syndrome, a condition that has troubled him since the end of last season. The French midfielder largely trained separately during the pre-season and missed the opening game of the Serie A campaign against Frosinone last week.
A specialist consultation next week will decide whether Thuram undergoes knee surgery. Sky Sport and Gazzetta report that he will fly to France to visit Bertrand Sonnery Cottet, a specialist who has performed knee surgeries on other Juventus players in the past.
Thuram's potential lengthy lay-off will further affect Juventus in the middle of the park, where they are already looking for a new central midfielder.
