Dustin Martin is taking time away from the club and is in doubt for the match against Greater Western Sydney at the MCG on Sunday.
Martin was a notable absentee from Thursday's run at Punt Road Oval and has not been at the club since Monday's match review, missing their Tuesday training session.
Richmond coach Damien Hardwick told reporters it was personal and when the time was right to share more information, "we'll share it".
"He's dealing with a couple of personal issues and whether he is available to play this week, we're unsure at the moment," Hardwick said.
"We won't close the door, but we just want to make sure that Dustin's OK ... we are a football club, and it is important to win games but the health and wellbeing of our players is our No.1 priority.
"We'll give him his time. He's so important to the fabric of our footy club, we just want to make sure he's OK and he's getting what he needs."
