Chelsea FC defender Davide Zappacosta has undergone successful surgery after tearing his anterior cruciate ligament in a training session.
Zapacosta was loaned out to AS Roma this season with the Italian club confirming that the defender will immediately start his rehabilitation process.
In a statement on their website, Roma noted: "The club can confirm that Davide Zappacosta underwent surgery on Friday afternoon to repair the anterior cruciate ligament in his right knee.
"The operation was carried out by Professor Mariani, at Villa Stuart private hospital in Rome. The surgery was a success and the player will start the rehabilitation process imminently."
The Italy international joined the Serie A outfit on loan until the end of the season on transfer deadline day after becoming surplus to requirements at Stamford Bridge.
It is unclear whether the 27-year-old, who has featured just once for Roma since arriving on loan, will return to Chelsea to continue his recovery.
Zappacosta joined the Blues in a £23m deal from Torino in 2017 but struggled to hold down a regular first-team place under Antonio Conte and Maurizio Sarri.
