Riise out of Portugal clash

OSLO - AS Roma defender John Arne Riise has been ruled out of Norway's Euro 2012 qualifier against Portugal in Oslo on Tuesday with suspected concussion.

Riise suffered the injury during a training session on Monday at the Ullevaal Stadium.

"He was unfortunate. He seems to have suffered a concussion, and he's been taken to hospital as a precautionary measure," Norwegian team spokesman Jon Moerland said.

"I haven't been fully updated but apparently it was a fair challenge between two players and his (Riise's) head clashed with the other player's shoulder. It was just an unlucky thing."

In their opening Group H matches, Norway beat Iceland 2-1 in Reykjavik and Portugal drew 4-4 at home to Cyprus.
