Lazio could be without both Miroslav Klose and Nenad Lulic for Thursday’s Europa League game against Panathinaikos.
The duo, according to Sky Sport Italia, missed this morning’s training session at Formello which has left their availability for Europe in doubt.
Boss Vladimir Petkovic may also take the decision to rest Brazilian international Hernanes ahead of the weekend’s game at Fiorentina.
Lazio top Group J with four points ahead of NK Maribor, Tottenham and Panathinaikos.
