Richmond has been dealt a double injury blow on the eve of the finals, with Ivan Soldo facing a lengthy stint on the sidelines with a knee injury and Tom Lynch suffering a hamstring strain.

Soldo limped off the field moments before half-time in the Tigers' strong win over Geelong on Friday night after hurting his left knee in a marking collision.

He didn't reappear for the night and coach Damien Hardwick said the 2019 premiership big man had suffered a 'significant knee injury'.

The injury could leave him eyeing a long spell out of the game after rising to become one of the leading ruckmen in the competition.

"Soldo we think has got a significant knee injury, we'll wait to confirm that via scans which is disappointing. He's been such an important player for us over the course of this year and last," Hardwick said post-game.

"Tom's got a hamstring, we're not quite sure of the severity of that at the moment, he'll probably have scans on that on Monday also.

"They're two big losses but we think we've got some players who can step up and fill the void. It provides opportunity [to] some guys back at our hub."

Hardwick feared the worst for the 24-year-old Soldo's knee injury.

"It's still pretty raw and probably won't settle in until tomorrow when he gets a better understanding of exactly what we're looking at," he said.

"For him to go down is incredibly disappointing for not only our footy club, but for Soldo and his family back home."

Lynch's setback is less serious but does leave him in doubt for Richmond's first final, which could be a qualifying final after the Tigers' 26-point win over the Cats.

It leaves the Tigers with the task of beating the 18th-placed Crows in round 18 to confirm a top-four spot, but Lynch could miss their first finals game with the finals expected to start 19 days from Friday. It is unclear at this stage when Richmond's first final would be staged in that run of games.

It was the only low point of a dominant performance for the Tigers, who kept Geelong to only one goal until three-quarter time and ended the Cats' run of six straight wins.
