Crystal Palace winger Jason Puncheon has been fined £15,000 by the Football Association for comments that he made on Twitter in relation to Neil Warnock.
The 27-year-old has also been warned over his future conduct after admitting an FA charge.
Puncheon deleted a series of tweets in January in response to criticism from Warnock for missing a penalty against Tottenham Hotspur.
"The charge was that in posting the comments, Puncheon failed to act in the best interests of the game and/or acted in a manner which was improper and/or used abusive and/or insulting words, in contravention of FA Rule E3(1)," read an official FA statement.
Puncheon joined Crystal Palace from Southampton in the summer.
