Jorge Andrade has left Juventus after enduring two injury-hit campaigns with the club.
The Portugal international joined Juve from Deportivo La Coruna in 2007 but has suffered two serious knee problems.
He missed almost all of last season and not played this term following a third operation.
Juventus said last year they feared he would never be fit enough to cope with the demands of professional football, and they have now released him from his contract.
Midfielder Hasan Salihamidzic, meanwhile, is facing a spell on the sidelines after undergoing knee surgery.
He picked up a knock in Sunday's 3-3 draw with Chievo and looks set to be out of action for around four weeks.
News of Salihamidzic's absence will come as a blow to boss Claudio Ranieri as Juve aim to keep pressure on Inter Milan at the top of Serie A.
