BELO HORIZONTE, Brazil (AP) Chile has injury concerns over key players Gary Medel and Arturo Vidal ahead of its second round match against Brazil at the World Cup on Saturday.
Chile coach Jorge Sampaoli says Medel has a muscle injury and the central defender's problem ''is not a minor problem. If the game were today, he wouldn't play.''
Sampaoli didn't specify the exact nature of the injury. Medel has been a key player in Sampaoli's defense, especially when the team has changed tactics, playing a 3-4-1-2.
Last month, Vidal had knee surgery, and then injured an Achilles tendon in Brazil. Sampaoli says while the powerful midfielder can play, but ''he's not close to 100 percent.'' Vidal started the first two group matches, but was an unused substitute in the 2-0 loss to the Netherlands.
