Czech international Nedved has been in a clinic since suffering concussion in Juve's 1-0 first leg defeat to Real in Madrid on Tuesday, when he clashed heads with Spanish defender Raul Bravo.
Juventus said
The Italian club said further tests would be made on March 8, just a day before the second-leg with Real, to decide when Nedved could begin training.
Juventus face Roma on Saturday in Serie A.
