Richmond coach Damien Hardwick insists Chris Yarran is an important part of the club's future despite the fact he is now on indefinite leave due to a mental health condition.

The Tigers released a statement on Thursday saying Yarran, who has yet to play a game for the club since his off-season move from Carlton, would be given time away from the club.

"With Chris' health and wellbeing the number one priority, no timeframe has been put on his return to football," the Tigers said in a statement.

"Chris, together with the club's medical and welfare staff, felt it was in his best interests to seek professional treatment away from the club.
