Bari dealt with an injury crisis throughout the campaign and 2011 starts on another sour note, as Paulo Vitor Barreto will be out for a month.
The Brazilian top scorer had just returned from six weeks on the sidelines when he picked up another muscular problem in training.
Tests have confirmed a right thigh strain that will keep him on the treatment table for around a month.
Teammates Salvatore Masiello and Abdel Ghezzal also have thigh injuries, although Nacho Castillo should be able to resume training with the squad.
Bari hope to have goalkeeper Jean-Francois Gillet back in time for Thursday's Puglia derby against Lecce.
Marco Rossi is suspended, while Alessandro Parisi, Gianluca Galasso, Sergio Almiron and Salvatore Masiello are all doubts.
