Newcastle assistant manager John Carver and Wigan coach Graham Barrow have both been fined for their part in a half-time melee.
The pair have been charged with misconduct by the Football Association, with the former being ordered to pay an undisclosed fee and warned over his future conduct, whilst the latter has been given a one-match touchline ban and fined €1100.
They came to blows after a challenge on Massadio Haidara by Callum McManaman went unnoticed by referee Mark Halsey, leaving the Frenchman on a stretcher.
Carver went to remonstrate with the striker, but Barrow intervened, pushing the Magpies number two before a few playing and coaching staff stepped in to put a stop to the scuffle.
McManaman has since escaped punishment himself, as an official saw the challenge and decided it did not warrant punishment, while the FA decided not to take retrospective action.
Statements from both clubs have confirmed the fines, with the Magpies saying: "Newcastle United assistant manager John Carver has been fined and warned as to his future conduct as a result of the charge brought against him by the Football Association following United's match at Wigan Athletic on 17 March 2013."
Wigan confirmed Barrow will be missing one game, stating: "First team coach GB has been fined £1,000 and given a one match touchline suspension with immediate effect after accepting an FA charge of misconduct following an incident at half-time in the match against Newcastle United at the DW Stadium on March 17."
