Juventus will be without winger Mauro Camoranesi and stopper Giorgio Chiellini for Sunday night's match with Lazio at the Olimpico.
The pair have not recovered from knocks as quickly as expected for the match against the seventh-placed Romans, where second-placed Juve will be hoping to make up more ground on leaders Inter.
The Turin giants moved within four points last weekend and could close the gap to a point if Inter loses at 11th-placed Atalanta earlier on Sunday.
Juve striker Vincenzo Iaquinta is waiting on a fitness test Saturday to know if he will make the squad.
