The forearm whack that concussed Adelaide's David Mackay has cost Richmond premiership star Josh Caddy a one-game AFL suspension.
Caddy will miss next week's match against Hawthorn unless he successfully contests the charge at the tribunal.
Tigers ruckman Toby Nankervis and Crows newcomer Darcy Fogarty were also charged with misconduct after Thursday night's clash and fined $1500.
The match kept match reviewer Michael Christian busy, with Crows captain Taylor Walker and Richmond onballer Shane Edwards cleared of incidents.
Christian also took no action against Tigers star Alex Rance after Walker pushed him in the back and the defender fell to the ground.
The match reviewer said the incident didn't warrant a charge of staging.
Caddy caught Mackay high in the third quarter and the midfielder was off the ground for the rest of the match.
Christian ruled the incident was careless conduct with medium impact to the head.
Nankervis was fined for falling heavily across Matt Crouch's back while Fogarty was fined in his second senior game for misconduct against Caddy.
Fogarty caught Caddy in the back with a swinging arm after the Richmond utility took a mark.
Richmond veteran Shane Edwards was cleared of an incident in which he braced himself for contact and his hip hit Walker's head.
Christian ruled Edwards had no realistic alternative as he contested for the ball.
