The Cameroon defender headed a late equaliser to earn the Canaries a 1-1 draw at Everton in the Barclays Premier League on Saturday and was believed to be the subject of racist abuse on Twitter later in the evening.
Norwich are aware of the comments and McNally tweeted on Sunday: "For those asking last night, we will be following up with the police regarding the racist comments reported after the game."
He later added: "Not relevant which team they support. Don't accept racism from anyone and so these comments will be reported to the police."
