Rangers midfielder Joey Barton has been suspended for three weeks, the club have announced.
On Monday, Barton ended a five-day enforced absence from the club with a meeting at Ibrox, where he is reported to have met manager Mark Warburton and board members.
The 34-year-old confirmed last week that he was told to stay away from the club for several days in order to "re-evaluate the way I'm thinking" following a heated argument involving teammate Andy Halliday in the wake of Rangers' 5-1 defeat to Celtic.
A club statement on Monday morning read: "JOEY BARTON has today been suspended by the club and will not return to Ibrox or Auchenhowie for a period of three weeks.
"The manager, Mark Warburton, and club believe that time and space is required for both the club and the player to assess all that has happened.
"Neither party will make any further statement or comment on this issue."

Speaking after he emerged from Monday's meeting, Sky Sports News had asked Barton whether he remained a Rangers player, but he replied only: "I think so."
Barton, who moved to Ibrox on a free transfer in the summer, was absent as Rangers continued their indifferent start to the season with a goalless Ibrox draw against Ross County on Saturday.
The midfielder lifted the lid on last Tuesday's training-ground dispute during a live radio interview on talkSPORT three days later.
Barton declared himself "as committed to Glasgow Rangers as the day I signed," but also implied criticism of the way Warburton had handled the situation and cast doubt on his desire to change his ways.
He said on Friday: "We're asked for an opinion and I'm someone who gives an opinion. Two passionate Rangers players have then shared opinions on how we get better as a team and what's going wrong for us. It's nothing more and nothing less than that.
"Obviously sometimes the way I communicate can be a bit blunt and a bit direct and it ruffles people's feathers, which I know I have to work at, but I don't apologise for trying to win. I care deeply about playing football."
Barton, who signed a two-year contract in the summer, added: "The way it's been handled is strange. When you look at my history and you're told to stay away from the club, it does look like something more has happened, and that's why I've decided to get on the radio and speak, because it's wrong."
At his pre-match news conference, Warburton was again asked about the situation but refused to be drawn into a discussion.
"It's not for me to make any further comment other than what has been released by the club this morning," he said. "That's all I'm going to say. I'm sure you can understand that from my position and the position of the club. The statement has gone out and no further comment will be made from the club."
He also declined to confirm whether Barton had been placed on paid leave, adding: "You can imagine that such details never come out and are never mentioned by me. Respect the fact we're not going to make any further comment."
But the Englishman did insist he will continue to carry out the type of postmatch debriefs which sparked the Barton row -- but stressed he will not stand for players overstepping the line with their comments.
He said: "The environment we create for the players and the staff is about giving respectful opinion. I always want opinion. I'll never have a problem with a player knocking on my door to talk about a session. Do it in the right manner or else they'll get a flea in their ear.
"It's about being respectful with the way we deal with each other. That's the way society is these days, it's changing. So I have no problem with [players expressing opinions] at all. It's how you deliver the message which will always be key to myself and my staff."
