Lee Hughes is at the centre of an internal investigation at Oldham after a club night out descended into a brawl.
Reports suggest that Hughes put his manager John Sheridan in a headlock during an informal 'meet the players' evening at Belle Vue Dog track on Tuesday, 24 February.
Reports suggest that goalkeeper Mark Crossley was forced to intervene in order to break up the confrontation. It has also been alleged that Sean Gregan had a bust-up with Chris Taylor during the same evening.
Oldham chief executive Alan Hardy has ordered a full investigation into the evening and has promised the "strongest possible action" against anyone who acted inappropriately.
Hardy added: "you can not discount sacking in this respect."
