Yo, Josh!
Law 14.1 states:
So not sure I agree with
@socal lurker about this only applying after the CR has blown for the kick to be taken. That's not stated anywhere in the LOTG.
In reality, the GK touching the crossbar and/or posts doesn't matter unless it interferes with the kicker. One could argue that this is anytime after the penalty is called and before the kick is taken because it causes wasted time. But in general it will have a bigger impact closer to the time the penalty is taken.
That means the closer to the kick the GK is touching the post/crossbar (especially after being told not to) the more they should expect a caution.
To trying to avoid this from happening altogether; he's my usual procedure for a penalty:
- Call for penalty
- Get all field players out of the box
- Have the kicker identify him/herself and tell them, "on my whistle."
- Walk to the GK (who's usually off their line), walk them back to the goal line and tell them no leaving the line until the ball is kicked and no touching posts/crossbar
- Walk back to my position next to penalty spot while checking AR is in the correct spot, all field players are outside of penalty box & arc.
- Whistle for kick to be taken
If a GK touches the post/crossbar
before step 4, I'm not worrying too much about it unless it's excessively distracting.
If it happens
after step 4, they've been warned and a caution is appropriate.
But I could also see a strong warning being just as effective if, say, the GK does a quick jump and brushes the post. Kindof depends on how much control over the game you have and if a caution will help you regain that control.
Like a lot of things, this is a subjective call. Use your best judgement!
Law 14.2 states:
So the penalty kick would only be retaken if the GK touching the crossbar/posts clearly impacts the kicker.
This is likely as the run up is happening. The kick would not be retaken if the GK touches the crossbar/posts before the whistle.
Hope this helps
