Keeper Boruc calls time on Celtic career
The Italian club announced on their website on Monday evening that the Poland keeper would complete his move to Italy after undergoing a medical.
Boruc had one year left on his contract and Celtic have opted to sell the 30-year-old rather than risk losing him for nothing next summer.
"The negotiations will be completed after the results of the medical."
The imminent departure of Boruc, who set off on the club's pre-season tour of North America on Monday morning, leaves compatriot Lukasz Zaluska as Neil Lennon's first-choice stopper.
Boruc made more than 200 appearances for the club after arriving from Legia Warsaw in 2005.
