Fremantle ruckman Sean Darcy has been placed on report following an incident involving Richmond's Nick Vlastuin during the second quarter of the Dockers' clash with the Tigers at Domain Stadium.
Darcy elbowed Vlastuin in the face after he handballed the ball.
He was placed on report by the officiating umpire and the Tigers received a free kick down field.
The Tigers lead the Dockers at half-time 11.2 (68) to 3.5 (23).
Meanwhile, Harley Bennell has four disposals and has kicked two goals so far in his first game for the Dockers following the best part of two seasons on the sidelines due to ongoing calf issues.
