Match review officer Michael Christian has laid several charges from Saturday and Sunday's round 21 games.

Crows skipper Taylor Walker has been handed a two-match suspension for his dangerous sling tackle on Giants midfielder Josh Kelly, meaning his season is effectively over if he does not challenge the ban.

Collingwood midfielder Levi Greenwood has escaped any penalty for negligible contact on Lions star Dayne Zorko.

The remaining charges are all financial sanctions, including:

-Aidyn Johnson can accept $2000 sanction for rough conduct on Tom Cole.

-Jarrad Waite can accept $3000 sanction for rough conduct on Jackson Trengove.

-Trent Dumont can accept $2000 sanction for rough conduct on Ed Richards.

-Dale Morris can accept $2000 sanction for tripping Jy Simpkin.

-Clayton Oliver can accept $1000 sanction for careless contact umpire C.Fleer.

-Dan Hannebery can accept $1500 sanction for misconduct against James Harmes.
