Norway´s Riise out of Portugal match with concussion

Norway left-back John Arne Riise has been ruled out of his side’s Euro 2012 qualifier with Portugal due to concussion sustained in training on Monday, the Norwegian football federation announced.

The Roma defender was hurt during a training session behind closed doors at the Ullevaal stadium in Oslo and was taken to hospital for routine examinations.

Riise, who is 29 and has 89 caps, injured himself in a collision with team-mate Espen Ruud and remained dazed on the ground for several minutes, according to Norwegian daily Verdans Gang.

Norway beat Iceland 2-1 in their Group H opener last Friday and on Tuesday host Portugal, who drew 4-4 with Cyprus in their first group match.
