Chile has injury concerns over key players Gary Medel and Arturo Vidal ahead of its second round match against Brazil at the World Cup .
Medel has a muscle injury and the central defender's problem "is not a minor problem," Chile coach Jorge Sampaoli said. "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 right knee surgery, and then injured his right Achilles tendon in Brazil.
Sampaoli said the powerful midfielder can play, but he's not fully fit.
