There are reports Inter midfielder Hernanes could be out for some time with a thigh strain.
The Brazilian arrived from Lazio for €20m on transfer deadline day and only made his debut on Sunday in a 1-0 win over Sassuolo.
He didn’t train with the rest of the squad today, as he is struggling with a muscular problem.
According to Sport Mediaset, there are strong fears Hernanes has suffered a thigh strain, which could keep him on the sidelines for at least three weeks.
It would be a heavy blow for the Nerazzurri, who finally got their first victory of 2014 at the weekend.
Mateo Kovacic also did not train today, as he required three stitches for a cut to his right knee.
Diego Milito and Esteban Cambiasso are not expected to be fit in time for the Serie A game against Fiorentina.
