Four players have been charged by the AFL's Match Review Officer from Saturday's Round 20 matches.

Brisbane star Josh Dunkley is one of two players to face MRO heat from the QClash, with the Lions midfielder being handed a charge for tripping Suns captain Noah Anderson.

Dunkley's actions have been graded as intentional conduct, body contact and low impact, resulting in a fine of $3000.

That penalty can be reduced to $2000 with an early plea.

From the same game, Suns forward Ben Ainsworth can reduce a $3000 fine for rough conduct on Lions youngster Jaspa Fletcher to $2000 with an early plea.

The incident from the opening term has been graded as careless conduct, low impact and high contact by the MRO.

Elsewhere, Fremantle forward Patrick Voss has been charged with rough conduct for an incident involving West Coast's Harley Reid.

Voss has been offered a $6250 fine, which can be reduced to $3750 with an early plea, after his actions were graded as intentional conduct, body contact and low impact.

Finally, Adelaide's Chayce Jones has been charged with rough conduct on Port Adelaide's Zak Butters from Saturday night's Showdown.

The incident in question occurred in the fourth term of Adelaide's heavy win, with Jones' actions graded as careless conduct, low impact and high contact by the MRO.

Jones can reduce a $3000 fine to $2000 with an early plea.
