BBC Scotland has revealed that Joey Barton will not report back for training at Rangers on Monday as planned and is now unlikely to play for the club again.
The 34-year-old was suspended from the club's training ground last month following a bust-up with teammate Andy Halliday and has not featured for the Glasgow-based side since.
The fallout of the very first incident, which occured when Rangers players were analysing their 5-1 thrashing at Celtic, has included Barton refusing to apologise to his manager Mark Warburton and even a Scottish FA charge for breaching gambling rules.

When the midfielder was asked to attend a club hearing this week, he refused, which is understood to have only heightened tensions and created a stalemate between both parties regarding the nature of the disciplinary process.
Barton, who remains on full play, moved north of the border on a two-year deal in the summer having helped Burnley clinch promotion to the Premier League, however his Rangers career may be over after just eight appearances.

The former Manchester City youngster was initially expected to return on 10 October but Scottish football's governing body then alleged that he'd breached rules by placing 44 bets on matches from 1 July to 15 September.
The rules state that the Scottish FA deems it misconduct should players, coaches, club officials or referees in the country bet on football or football-related activity anywhere in the world.
As a result of that revelation, Rangers announced that they had informed Barton to stay away from the club for another seven days while they launched a "formal disciplinary procedure" in relation to his behaviour.
He asked for more time in order to further consider the charge against him but a hearing has now been scheduled for 17 November. Without Barton, Rangers have won three and drawn one of their five games in all competitions.
The Englishman, who holds one cap for his country, has also represented Manchester City, Newcastle United, Marseille and Queens Park Rangers, and played 417 times in his senior club career, scoring 36 goals.
