Italy centre-back Giorgio Chiellini's continued participation at UEFA EURO 2012 is at risk due to a hamstring injury.

The 27-year-old limped out of his nation's 2-0 win over Republic of Ireland on Monday night, and team doctor Enrico Castellacci admitted afterwards that the signs weren't good.

"These injuries never have immediate recovery periods but we'll have to wait for the tests we'll conduct in a couple of days," he said.

Coach Cesare Prandelli was more positive, expressing his belief that Chiellini would make Sunday's quarter-final in Kiev.

"I have faith in our great physios and medical staff to get him ready," he said.
