Inter Milan's Romanian international defender Cristian Chivu fractured his skull and was taken to hospital on Wednesday during his side's 1-0 victory over Chievo.
Chivu suffered the injury just after half-time in a clash of heads with Chievo player Sergio Pellissier. He was later operated on for just over an hour after receiving a visit from his team-mates and the surgeon said he was optimistic he would make a full recovery.
"We are pretty confident that the patient will recover without a problem," said Professor Sergio Turazzi. "It is premature to say when he can leave hospital. But there is every hope that everything will be resolved in the best possible way."
Inter coach Jose Mourinho had said earlier that he believed Chivu would be fine but unable to play for a long time. "He has fractured his skull and we hope he will be able to recover very quickly, even though I fear he will be on the sidelines for a while."
