Carlton defender Tom Williamson has taken an indefinite leave of absence from the AFL club to deal with personal issues.
The 23-year-old has featured in one senior game this season, as an unused substitute against Richmond in round one.
In a club statement on Monday night, the Blues said they had been supporting Williamson for several months as he dealt with "a number of personal issues".
"It has been agreed by all parties that it would be best that Williamson takes extended time away from the football club to focus on his wellbeing and ultimately address his personal issues," the statement read.
"The wellbeing and the health and safety of all remains the club's priority and due to the sensitive nature of this matter, the club is not in a position to provide any further comment at this stage."
Williamson has played 44 games for Carlton since being selected with pick No.61 in the 2016 national draft.
