New signing Luca Toni suffered an ankle injury in the 2-0 win.
The official Juventus website has confirmed Toni "sprained the medial section of his right knee.
"Tomorrow he will undergo further tests."
Even if it is just a sprain, Toni is effectively out of this weekend's Serie A match with Bari.
If the knee ligaments are affected by the injury, then he could be out for several weeks.
