Clip 4 - 9 June 2018 Law 11
Knock on, no try. Why? -
This is just to reinforce a point.
The Rebels are on the attack. Prop Fereti Sa'aga charges ahead till Ofa Tu'ungafasi, a Blues prop, tackles him. Sa'agaa haws two team-mates close by - Marika Koroibete to the right and Colby Fainga'a to the left. Sa'aga tries to pop a pass to a team-mate and the ball ends in the possession of Fainga'a who battles his way over the line where he grounds the ball.
The referee refers the transfer of the ball to the TMO, who reports that the ball struck Koroibete's arm on its way to Fainga'a.
Knock-on: When a player loses possession of the ball and it goes forward, or when a player hits the ball forward with the hand or arm, or when the ball hits the hand or arm and goes forward and the ball touches the ground or another player before the original player can catch it.
There it is. The ball hit Koroibete's ARM and went forward, which constitutes a knock-on.
