Juventus veteran Andrea Pirlo has handed coach Max Allegri an injury headache.
Pirlo suffered a calf injury in their 2-1 Champions League win over Borussia Dortmund.
"He went off with a calf problem and will be evaluated tomorrow morning. We'll see," said Allegri.
Pirlo is now in doubt for this weekend's clash with AS Roma.
