Here's a rundown of key players who may miss the World Cup – or at least the opening matches.
ITALY: Pirlo, winner of the Bronze Ball in the 2006 World Cup, was integral to Italy’s championship at that tournament in Germany. But his potential absence isn't the team's only concern. Midfielders Mauro Camoranesi, Claudio Marchisio, and Angelo Palombo are facing injuries, according to Sky Sports.
IVORY COAST: Didier Drogba broke his forearm Friday and underwent surgery Saturday. He is one of the world's top strikers and highest paid players (as a member of English Premier League champions, Chelsea). Mr. Drogba hopes to return in time for the June 15 opener against Portugal.
