A trio of AFL players were fined for "careless contact with an umpire" during Sunday's clashes, resulting in $1,500 ($1,000 guilty plea) fines.

Richmond's Kane McAuliffe, West Coast's Brady Hough and Brisbane's Josh Dunkley were all penalised for the same offence.

All three players were sanctioned for the first time, meaning the fee remains low.

Eagles forward Tyler Brockman was the fourth player charged with an offence in Sunday's matches.

Brockman was penalised for striking Tigers defender Luke Trainor in the first quarter.

The Match Review Officer (MRO) didn't deem the action gradable, but still handed down a $1,500 ($1,000 guilty plea) fine.

Earlier in the weekend, Essendon's Will Setterfield was fined for tripping Sydney star Isaac Heeney.

The MRO deemed the incident as intentional conduct, low impact and body contact, resulting in a $3,000 ($2,000 guilty plea).

Friday's contest between St Kilda and Carlton also saw another three players penalised for their behaviour.

Saints youngster Hugh Boxshall was charged, for the second time, for carelessly coming into contact with an umpire. He was fined $3,125 ($1,875 guilty plea).

Rowan Marshall was charged with attempting to trip Blues tall Nick Haynes, warranting a $1,500 ($1,000 guilty plea) fine.

Carlton midfielder George Hewett also received scrutiny from the MRO, copping a $6,250 ($3,750 guilty plea) fine for tripping Ryan Byrans in the first quarter. The incident was graded as intentional conduct, low impact and body contact.
