Italy will make a decision on 13 June whether or not to call up a replacement to their FIFA World Cup squad for Andrea Pirlo, who suffered a calf injury in the world champions' 2-1 loss to Mexico on Thursday. The Azzurri medical staff expect the AC Milan midfielder to be sidelined for "15 to 20 days", ruling him out of his team's Group F opener against Paraguay in Cape Town on 14 June. "He will probably travel to South Africa but will, for sure, miss the first game," said Enrico Castellacci, Italy's head doctor.
