Odell Beckham Jr. will miss the New York Giants' game against the Minnesota Vikings on Sunday after the NFL upheld his one-match suspension.
NFL appeals officer James Thrash ruled on Wednesday that the star wide receiver's actions against the Carolina Panthers last week warranted a ban.
Though Beckham engaged in a personal battle with Carolina cornerback Josh Norman throughout the Panthers' 38-35 win, a late helmet-to-helmet by the receiver was his major offence.
In a statement, the NFL cited "multiple violations of safety-related playing rules" as the reason for rejecting Beckham's appeal.
NFL officiating chief Dean Blandino said Tuesday that Beckham should have been ejected from the game.
