SSC Napoli will be without Ezequiel Lavezzi for around four to five weeks after the forward strained his right thigh during the 3-1 home defeat by AS Roma on Sunday.
The 26-year-old was replaced by Goran Pandev 11 minutes into the second half at the Stadio San Paolo and, following tests, is not expected to return until late January. The Argentinian international has scored three goals in 14 top-flight appearances this term for Walter Mazzarri's side, who are ninth in Serie A.
Lavezzi started all six of the Partenopei's UEFA Champions League Group A matches. Napoli's reward for finishing second in that section is a round of 16 tie against Chelsea FC, the first leg of which takes place in Italy on 21 February.
