Striker Humberto Suazo seems certain to miss Chile's first match at the World Cup after suffering a hamstring injury.
Suazo picked up the injury in a friendly match against Israel on Sunday, in which he scored a goal. Medical reports released Wednesday said Suazo, who is Chile's leading striker, may need up to three weeks to recover.
Chile, appearing in its first World Cup since 1998, faces Honduras in its Group H opener on June 16. It plays Switzerland on June 21 and Spain on June 25.
Esteban Paredes will be the leading candidate to replace Suazo, who plays in Spain for Zaragoza.
