Juventus expect Juan Cuadrado to be out of action for at least another month after undergoing surgery on a groin injury.
Cuadrado will miss the first leg of Juve's Champions League last-16 tie with Tottenham on February 13 but has a chance of returning to action in time for March 7's second leg.
The Colombia international, who has scored three Serie A goals in 11 starts this season, has already been out for five weeks.
"Juan Cuadrado underwent surgery today [Tuesday] on a long-standing groin problem," a Juve statement read.
"Upon returning to Italy the player will immediately start his rehabilitation programme, with a period of about 30 days rest being foreseen as necessary before he returns to training."
Juve, on an eight-match winning streak in all competitions, travel to Atalanta for the first leg of their Coppa Italia semi-final on Tuesday.
