Sydney's Brodie Grundy has been charged for striking opponent Tim English in Thursday's win over the Western Bulldogs.
The incident took place in the first quarter of the Round 11 match, with Grundy's actions graded as intentional conduct, body contact and low impact.
It also cost the Swans a 50-metre penalty.
That grading has resulted in a fine for Grundy, who can accept a $2500 sanction with an early guilty plea.
If Grundy chooses to challenge the charge and fails, he would be required to pay $3750.
No other players were cited from Thursday's game between Sydney and the Western Bulldogs.
