A knock-on occurs 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.

Now the ref gives a knock on, the opposition supporters behind me say 'what was he doing thats an obvious knock on'... but in my eyes the player didnt try to gain possession by use of arms, the ball doesnt hit hand or arm..... so is it a given if the ball goes forward off any part of the body but the legs its a default knock on? and in the incident above is there any ambiguity?

If this trajectory is not clear and evident, the direction of the hands could help the decision." So this notion on boards.ie that the direction of the ball doesn't matter, only the movement of the hands, is hopefully finished.

former legend wrote: » Yes, definitely, but there have been cases recently (e.g. the Munster v Perpignan game) where the ball has clearly gone forward out of a player's hands and posters here have been saying "it doesn't matter, his hands went backwards". The key point here is that trajectory of the ball relative to the passing player is the main focus, not the direction of his hands.

A ball slightly going forward could be due to a hand-slip, wind, the way the ball spins, any number of things.

The player then passes the ball to a teammate who is running parallel and a couple of metres behind. While in the air, lets say that the ball is travelling at y m/s, but in a different direction. Treat the velocity of the ball during the pass as a vector, and resolve it into two components, one perpendicular to the touchline, and one parallel to the touchline. Call the parallel component z. Now, some people seem to think that z has to be negative for a pass to be backward. It doesn't. As long as z < x, the pass is backward. If the ball is moving towards the opposing line at 10 m/s in the player's hands, and is moving towards the opposing line at 5 m/s during the pass, then that's a backward pass.

Charge down. If a player charges down the ball as an opponent kicks it, or immediately after the kick, it is not a knock-on even though the ball may travel forward.

Orlaw3136 wrote: » I get what you're saying but...if wind blows ball forward :pac: On a serious note the point is that if the passer is stopped immediately on passing the pass can look very obviously forward relative to the two players because the receiver will indeed catch it ahead of the passer, whereas if the passer ran on it wouldn't look problematic at all. Assuming the ball was passed backwards from the passer's perspective neither would be a forward pass.

Ive never gotten away with it mind you with the ref calling it back for a knock on. Was wondering if by the letter of the law this should have been a drop kick?
