Italy are doing 'everything possible' to get injured trio Daniele De Rossi, Ignazio Abate and Giorgio Chiellini back to fitness for Thursday's Euro 2012 semi-final against Germany.
The three players are all doubts for the Warsaw clash, even though Chiellini has returned to training after a thigh problem.
Midfielder De Rossi and right-back Abate were substituted with muscle injuries in Sunday's quarter-final victory over England.
The trio are undergoing intensive physiotherapy and the Azzurri's team doctor, Enrico Castellacci, said: "We are doing everything possible."
Chiellini missed Italy's win on Sunday but would probably come in for Leonardo Bonucci if he is fit for the semi-final.
Should De Rossi miss out he would likely be replaced by Antonio Nocerino, while coach Cesare Prandelli has a big decision to make if Abate fails to recover in time for Thursday.
Fellow right-back Christian Maggio is suspended so Prandelli could either move a centre-half like Bonucci or Andrea Barzagli to the right or change to a three-man defence used in the opening two group games.
