The injury suffered by Chilean midfielder Arturo Vidal at his club, Juventus of Italy, caused concern in the Chilean Football Federation, which sent a doctor to Europe to know the severity of the injury.
"We sent a representative to Italy to analyze the severity of the knee injury and see about his recovery," said Sergio Jadue, president of Chilean football, to the local and international press.
Vidal, an essential part of the Chilean team, suffered a sore knee that kept him out of the semifinals of the Europa League against Benfica.
"Arturo is playing matches in the Italian league and the Europa League. Also the matches for the national team, both friendly and official. We have to be patient," Jadue said.
Jadue described as "a good rest" the time that the midfielder is sidelined, and hopes to know the severity of his injury after the examinations to be held on Friday in Turin.
Chile debut in the World Cup on June 13 against Australia in Group B, which also includes Spain, the defending champion, and the Netherlands, the runner-up.
