Watford defender Ryan Andrews has been given a one-match ban for his reaction following his sending off against Sunderland earlier this month.
The 19-year-old was shown a red card for a late tackle on Jack Clarke in the 87th minute as the Hornets were beaten 2-0 at the Stadium of Light.
He denied an improper conduct charge, but was found guilty by an independent regulatory commission.
Andrews, who has made 10 appearances so far this season, was also fined £500.
