Michael Firrito has accepted a $1,000 sanction for striking the Lions’ Allen Christensen.

The defender made contact with Christensen during the second quarter of Sunday’s match at Etihad Stadium.

The incident was graded as 'intentional conduct with low impact to the body', resulting in a $1,500 sanction.

By accepting an early plea, the penalty was reduced to a $1,000 sanction.
