Richmond coach Damien Hardwick hopes the AFL match review panel have Essendon's David Hille in their memories on Monday when they assess a charging report laid against Richmond young gun Trent Cotchin.

The exciting 20-year-old midfielder looks likely to miss Saturday's MCG clash with Collingwood, after being booked on Sunday over an incident which left North Melbourne's Sam Wright requiring a hospital visit.

Wright marked in the middle of the ground, before Cotchin arrived late and crashed into him, with the Kangaroos youngster helped from the field with concussion, before being taken to hospital for a check-up.

The Kangaroos goaled from the resultant 50m penalty, sparking a charge which gave them control of the match and coach Brad Scott said the incident had been a spur.

"The guys got a bit of a spark, no one likes to see one of their teammates go down like that," Scott said.

He added there was no lingering ill-feeling towards Cotchin, who he said was a "ball player" and had made a "split-second decision".

Hardwick also emphasised the short timeframe players had to judge whether to make contact.

"It is a hard one and the game is played at breakneck speed," he said.

"From our point of view, we'll just let the tribunal handle it, we just hope (the match review panel maintains) the consistency level that they've adjudicated that one over the course of the season.

"It's very similar to the David Hille incident earlier in the year, so we'll see how that one pans out."

Hille was surprisingly cleared by the panel, after being cited for charging Geelong's Jimmy Bartel in the opening round, one of three incidents this season in which he has been the subject of a match-day report, but reprieved by the panel.

The Tigers will already be missing fellow midfielder Daniel Jackson, as he serves out a suspension, while another centre square player Nathan Foley is out injured for the rest of the season, adding to the significance of the Cotchin decision.
