Sweden coach Lars Lagerback has played down a training ground injury to goalkeeper Andreas Isaksson as nothing too serious.

The Rennes gloveman landed awkwardly during training on Sunday, but Lagerback says the problem is not serious enough to call into question his participation in the imminent World Cup campaign.

"He landed on his buttocks after he tried to catch the ball," Lagerback said.

"Team doctor Anders Valentin told me it was nothing serious after the first medical examination.

"In the worst case, it could be some kind of small bleeding, but most probably he'll be able to practice again tomorrow."
