Ben Griffiths has been ruled out 'indefinitely' after receiving yet another head knock.
His latest setback occurred during the VFL game between Richmond and Sandringham last weekend.
It's Griffiths' second concussion of the year already, the first coming in round two of the AFL against Collingwood.
Neil Balme, head of football at Richmond, has spoken about the incident from the weekend.
“It was a reasonable collision but it probably wouldn’t have affected nine out of 10 blokes,’’ he explained.
The Tigers will now seek the advice of specialists, and will take every precaution due to the nature of the injury.
Due to having a history of head injuries, Griffiths wears a helmet every game he plays. It is believed he has suffered at least 5 concussions while at Richmond.
Teammate Jack Riewoldt labelled Griffiths injury past as, "extremely scary".
"He's going to get some cognitive testing," Riewoldt said on RSN927 on Thursday morning.
"He'll be out for a prolonged period, which is the case when you have multiple injuries in any area.
"The club certainly aren't putting any pressure on him to get better quickly or anything like that, it's just do what's right for him and what's right for his health."
Richmond will now look to other options to play as a key forward next to Jack Riewoldt. Options seem limited after losing Ty Vickery in the preseason.
Todd Elton played against Melbourne in round five, however, only managed seven disposals and couldn't hit the scoreboard.
Other potential options include, Mabior Chol who kicked three goals in his last VFL appearance, or little known ex-basketball player Ivan Soldo, who stands at 204cm.
On Sunday afternoon the Tigers will play fellow unbeaten side Adelaide.
