Joey Barton will hold talks with Rangers on Thursday in a bid to resolve his future.
Barton has suspended since a training ground bust-up in September and it is unclear whether he will play for Rangers again.
He has recently been linked with a return to Burnley, but apparently no discussions have taken place between Barton and his former club.
Barton joined Rangers in the summer from Burnley, signing a two-year deal in July said to be worth £20,000 a week. He reportedly turned down a £35,000-a-week offer from the Lancashire club to move to Scotland.
His refusal to apologise and an unsanctioned live radio interview saw his initial seven-day exclusion extended by another three weeks.
The one-time England international claimed he would prove himself to be the best player in Scotland after securing his move to Rangers, but he failed to make an impact in the eight appearances he has made to date.
Despite being told to stay away from the club, Barton has stated repeatedly that he wants to return and fight for his place. Reports also claimed he had even flown to Qatar to take part in a boot camp designed to have him operating at peak fitness ahead of his return to Warburton’s squad.
Barton is, meanwhile, also being investigated by the Scottish Football Association over allegations he broke strict betting rules. He was charged with placing 44 bets on games between 1 July and 15 September this year.
