FEBravo Reuters seems to have mistranslated some news they got from Norway. Capacity will be reduced by 3000, not to 3000. The capacity is ordinarily 27 000 or so, and the match is sold out.
I have mixed feelings about boycotting vs not - I'll be going to the game to support Norway. I think Israel should be disqualified just like Russia were, but I'm not boycotting their away match to Norway. At the very least, the supporter club, including me, will bring a huge banner with names of Palestinian kids in cooperation with Amnesty's Let Children Live campaign.
