Milan may be without Thiago Silva and Clarence Seedorf for their Week 8 game at Lecce on Sunday.
Whispers coming out of Milanello suggest that the two are major doubts for this weekend because of fitness concerns.
The pair trained away from the squad on Friday and they'll face late fitness tests before a decision is made on whether or not to include them in the squad.
Alberto Aquilani and Kevin Prince Boateng also took part in personalised sessions, but they are expected to be ready.
Massimo Ambrosini returned to full training, but his recovery may have come too late for use at the Stadio Via del Mare.
