Internazionale winger Luis Figo is facing at least two months out after fracturing his right leg.
The Portuguese star suffered the injury in the second-half of Sunday's 1-1 Serie A draw with Juventus in Turin on Sunday.
He went under the surgeon's knife on Tuesday and the club's doctors say the surgery went well.
The 35-year-old is now set for a period of rehabilitation but is not expected to return until the end of January.
Figo's loss is a major blow to Inter boss Roberto Mancini, whose side currently top Serie A by a point and are top of UEFA Champions League Group G.
Mancini is already without a host of key players including Marco Materazzi (thigh), Patrick Vieira (calf), Dejan Stankovic (ankle) and Francesco Toldo (foot).
