Dustin Martin is firming for a finals return after completing his heaviest training load yet since his hamstring injury.

Martin hasn't played since suffering a hamstring injury in round 16, but is building towards a return and spent time back in Richmond's main training group, as well as working hard alone, a week out from their elimination final against Brisbane.

"He did a bit of training here today, and we have another session on Saturday, so hopefully he can do a bit more then," ruckman Toby Nankervis said.

"We will know more next week but, hopefully, he does (face Brisbane).

"Yeah probably (this is the most main training Martin has done) for a while.

"He's been doing a mountain of work away from the group, he's been training really well with the rehab group but to have him back in the main group gave everyone a really big lift.

"So hopefully more training in the next couple of days."

During a training drill, Noah Cumberland attempted to kick the ball but caught the leg of a smothering teammate.

The small forward, who has booted 18 goals in eight games and 12 in the past month, required assistance to leave the ground.

Nankervis played down Cumberland's injury concerns while the Tigers are confident he would be okay to face the Lions.

"I missed the last bit of training but I just spoke to him briefly and I think he should be alright," he said.

"We'll find out more this arvo but I think he should be right."

Tom Lynch is expected to play after being cleared of a serious groin injury but Jack Graham (toe) appears less likely to feature.

To snare a fourth premiership in six years, Richmond will have to take the long way via an elimination final, but triple-premiership player Nankervis was confident the Tigers had the mettle.

"It's different but we've given ourselves a chance," Nankervis said.

"Really grateful to be playing footy at this time of year.

"It's so hard to get to the finals and give yourself a chance and I think any team within the eight is a real show, especially this year, with the evenness of the competition, which is great.

"It's different than being in the top four but we're still as much a chance as anyone."
