If you are the OP, don't read this.
However, if you are an experienced ref, you will know that if Team A kicks the ball in-goal and a Team B player picks up the moving ball in-goal while having a foot in touch, then there is an option of a 22DO or a scrum where the ball was kicked. Equally, if the ball itself went THROUGH in-goal to go beyond either the Touch-in-Goal or Dead Ball lines, then the same option applies. Others that may apply but not (as Ian makes clcear) in this scenario of a grubber: If a kick-off, restart or 22DO is kicked into in-goal without touching another player and is then immediately made dead by Team B, the options are kick again or a scrum at the place of the kick. Also, if the kicker from Team B failed to kick the ball out of in-goal, and it was collected by a team-mate closer to the goal line and then grounded, that team-mate is offside and a PK is awarded on the 5m line. Equally, if the Blue player caught the ball on the full in in-goal and shouted MARK, the mark is awarded as a FK on the 5m line. There may be others.
Got a laugh out of this.
Ian, did you think Dixie was telling the OP not to read your post #6?
I took Dixie's post as continuing on from your post #6 but advised the OP not to read Dixie's examples for fear of confusing him at such an early stage.
Dixie, have I interpreted that correctly?
