ANDREW McQualter won't ask Toby Nankervis to adjust his aggressive approach despite it landing Richmond's physical ruckman in hot water over a high bump on Sydney's Jake Lloyd.

Nankervis will come under scrutiny of the Match Review Officer for the hit that concussed Lloyd during the second quarter of the Tigers' 13-point win at the MCG on Thursday night.

Lloyd was flattened and play was eventually paused while he was assessed by medical staff before he jogged off the ground under their watch.

The Swans defender was substituted out before half-time and will miss next week's clash with the Western Bulldogs under concussion protocols.

Nankervis went on to be one of Richmond's most influential players as they overwhelmed Sydney after half-time, posting a victory that puts them on the verge of the top eight.

But the Tigers co-captain looks set for a stint on the sidelines, with Richmond to face West Coast, Hawthorn and Melbourne in a crucial stretch of matches over the next three weeks.

"Toby's greatest strength for a long period of time (has been) his ability to get after the ball and the opposition," McQualter said.

"Whatever comes of it comes, but we wouldn't change Toby for the world.

"I thought Toby had a great game ... as a captain he led the way with what he did, particularly in the first 15 minutes of that third quarter.

"He was really significant."

The fallout from Nankervis' bump, which robbed Sydney of one of their chief playmakers, sparked calls from Brownlow medallist Adam Cooney for a send-off rule to be introduced into the game.

Sydney coach John Longmire wouldn't buy in to the send-off rule discussion.

"You can't do anything about it. Suck it up," Longmire said.
