The Football Association rejected Everton's appeal against Idrissa Gueye's red card without providing an explanation, David Moyes has said. Gueye, 36, was shown a straight red card for slapping his own team-mate, Michael Keane, in Everton's 1-0 win at Manchester United on Monday. Everton goalkeeper Jordan Pickford separated the clashing pair before referee Tony Harrington dismissed Gueye in the 13th minute.
