Juventus have suffered a blow ahead of this weekend's match against Bologna after Alberto Aquilani picked up an injury in training.
The Italy international midfielder developed a muscle problem, which the Juventus medical staff fear could be a strain of the adductor in his right thigh.
Aquilani will undergo a scan tomorrow morning to determine the severity of the injury.
Juventus boss Gigi Del Neri now has a potential selection headache in midfield as Aquilani joins Momo Sissoko on the sidelines.
It's thought that he will play Felipe Melo and Claudio Marchisio in the middle with Milos Krasic and Jorge Martinez on the flanks.
