The Real Madrid forward Cristiano Ronaldo missed Portugal's football friendly against Mexico as he continues to battle leg injuries.
Midfielder Raul Meireles and central defender Pepe also sat out the match in Boston, won 1-0 after a stunning last-gasp header by Portugal's Bruno Alves.
Ronaldo is suffering from an injury to his left thigh as well as patellar tendinosis, Meireles has an injury to his left thigh and Pepe a muscular injury in his right leg.
Ronaldo has yet to take part in a full training session with his team-mates since joining the Portugal camp one week ago, and also missed last weekend's friendly with Greece.
Portugal's opening World Cup match is against Germany in Salvador on June 16th - they also face United States and Ghana in their group.
