Nikola Maksimovic is a major doubt to face Genk in the Champions League on Tuesday, as he pulled up during Napoli training.
The Partenopei need at least a point against the Belgians at the Stadio San Paolo to qualify for the Round of 16.
Maksimovic was expected to start, either in central defence or as a right-back, but he left today’s training session early with a muscular problem.
A statement from Napoli confirmed he suffered an issue with the right quadricep.
Allan, Faouzi Ghoulam and Lorenzo Tonelli are also still training separately, with Arkadiusz Milik out of action.
Carlo Ancelotti's men were held to a 1-1 draw by Udinese last night, so are without a win in nine competitive games.
