Norwich has reported "racist" Twitter comments made after the Canaries' 1-1 draw with Everton. It is understood the tweets were made after Sebastien Bassong scored a late equaliser at Goodison Park on Saturday.
Chief executive David McNally tweeted on Sunday: "We will be following up with the police regarding the racist comments reported after the game."
He added: "Not relevant which team they support. Don't accept racism from anyone."
