Joao Cancelo has undergone successful surgery on his right knee, Juventus have confirmed.
The Portugal international had a medial selective meniscectomy at the Clinica Sedes Sapientiae in Turin on Friday.
The full-back is expected to be out of action until at least the middle of January.
Cancelo has been one of Juve's standout performers since joining from Valencia in a €40.4million deal.
He has made 15 appearances in all competitions for Massimiliano Allegri's side.
The Serie A leaders, who have won 14 and drawn one of their first 15 league games this term, face city rivals Torino on Saturday.
