Costa has hamstring tear

Madrid - A doctor treating Diego Costa for a hamstring injury says the striker has a muscle tear that needs to be reassessed in 15 days, raising doubts about his chances of making Spain's Soccer World Cup squad.

Pedro Guillen of the Cemtro clinic said in an interview with the Cadena Cope radio station that the 25-year-old Brazil-born player had a "grade one tear to the femoral biceps of his right leg," and would need 15 days convalescence before his injury could be re-evaluated.

Spain's opener in Brazil is on June 13 against the Netherlands.

Coach Vicente del Bosque said on Sunday the players in his 23-man squad would need to be fit by June 2 - the FIFA deadline for squad lists.
