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 on Monday that after undergoing tests Nedved had been released from the clinic but needed seven days of rest at home.
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.
