Crystal Palace winger Jason Puncheon has been slapped with a £15,000 fine from the FA.
The 27-year-old was hit in the pocket after posting derogatory comments about his former boss Neil Warnock on Twitter.
The spat began when Warnock, who signed Puncheon on loan while at QPR in 2011, criticised the Palace man after his penalty miss against Tottenham Hotspur in January.
Warnock, who made his criticisms of the penalty on radio station Talksport, said: “There’s no way I would have trusted him [Puncheon] with a penalty.
"You’ve got to have somebody a little bit more cool, and he’s not like that, Jason.”
Puncheon responded: “As a man I will live with that [banter and opinions], which is fine, but I will not live with [Warnock’s] opinion.”
The FA said Puncheon had “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”.
