Rangers' Fernando Ricksen has been commended for seeking the residential treatment that will see him enter the Sporting Chance Clinic on Monday.
Fernando Ricksen has had a troubled career
The defender will be treated in London for "anger and behavioural management".
Clinic chief executive Peter Kay said: "He contacted us several months ago and has got to the stage where he has decided to have residential treatment.
"He has embarked on everything up to now with gusto and Rangers must also be commended for supporting the player."
Kay had been working with Ricksen for the past six months, but treatment will intensify after the Dutchman was sent home from Rangers' pre-season trip to South Africa.
The 29-year-old had an alcohol-fuelled argument with a stewardess on the outward flight.
Fernando is in a place where he is full of remorse and regret

"He cannot equate the person who behaved as he did on the plane with the person he knows he is," said Kay.
"Remorse is very much on the menu at the moment.
"We are very much interested in working with him on his future and getting him back to playing to the standard he is used to and becoming the man he knows he can be.
"At first, he thought one-to-one counselling would support him enough and I travelled up to Scotland on several occasions.
"Now this has happened and he has taken the step to get further treatment.
"Sometimes these things happen - as tragic and sad as they are - for a reason.
"Fernando is in a place where he is full of remorse and regret, but he is also a lighter weight this evening than he has been for the last few weeks."
Ricksen will continue his pre-season training at the clinic while undergoing an initial, week-long assessment.
