Juventus defender Giorgio Chiellini is a doubt for the game against Milan on Sunday because of injury.
The centre-back put in an impressive display against Chelsea on Tuesday, but he limped out of the 3-0 win in the closing stages.
Chiellini suffered a minor calf strain which, according to the Gazzetta dello Sport, is still causing him discomfort.
The former Fiorentina player will continue to receive treatment over the next four days in an effort to have him ready for the San Siro clash.
The 28-year-old, who missed the start of the season because of fitness issues, has played in 11 League games this term.
Juventus boss Antonio Conte could turn to Martin Caceres, Lucio or even Luca Marrone if Chiellini is ruled out of action.
