Park Ji-sung looks set to miss South Korea's friendly against Norway on Friday after damaging an ankle in training.

The Manchester United midfielder suffered the injury in a collision with Lee Young-pyo, but team doctor Kim Hyun-chul does not believe the condition is serious enough to threaten his participation at the World Cup.

"At the moment, it looks like he has sprained his left ankle," said Kim.

Kim Nam-il is also expected to miss Friday's game in Oslo after taking a knock to his right ankle in training on Monday.

South Korea take on Ghana in another warm-up game on June 4, before getting their finals campaign underway against surprise qualifiers Togo on June 13.
