Fabricio Oberto withdrew from the Argentinian national team shortly before training camp, citing personal reasons.
"He told me he could not solve his personal problems and can´t play at the South American Championship," Argentina coach Sergio Hernandez said. "It is sad ... I noticed him affected because it is not what he wanted, but he can´t do anything and I understand him."
Oberto, 37, won an Olympic gold medal as a member of Argentina's national team in 2004.
