Newcastle manager Alan Pardew has been warned as to his future conduct after media comments he made prior to the match against Sunderland on 20th August.
Pardew was charged by the FA with improper conduct after comments regarding how Howard Webb would treat then Newcastle midfielder Joey Barton.
He said: "In a gameplan, Joey would get a mention so the ref needs to make sure he referees from a completely neutral point of view."
The Newcastle boss denied the charge and requested a personal hearing but the FA confirmed on Tuesday that the case had been found proven and Pardew has been warned as to his future conduct.
The Magpies beat Sunderland 1-0 in the game which saw seven yellow cards, including a sending off for Black Cats full-back Phil Bardsley.
Barton picked up a yellow card for dissent in the second half.
Pardew's warning comes after the FA introduced new rules this year preventing managers from speaking about match officials before a fixture.
