Chile are sweating over the fitness of striker Humberto Suazo, who is reportedly suffering from a muscle injury.

The 29-year-old, who was top scorer in Chile's qualifying run for the world finals, suffered the problem in a 3-0 friendly win over Israel, according to reports in the country.

It is just over two weeks until Chile's first game of the 2010 FIFA World Cup South Africa™, against Honduras.

European champions Spain and Switzerland are the other teams in their group.
