(b) Unintentional knock-on or throw forward at a lineout. A scrum is awarded 15 metres from the touchline.
(c) Knock-on or throw forward into the in-goal. If an attacking player knocks-on or throws-forward in the field of play and the ball goes into the opponents’ in-goal and it is made dead there, a scrum is awarded where the knock-on or throw forward happened.
(d) Knock-on or throw forward inside the in-goal. If a player of either team knocks-on or throws-forward inside the in-goal, a 5-metre scrum is awarded in line with the place of infringement not closer than 5 metres from the touchline.
