Pull up a chair fellow referees - true story this.
After reading this thread yesterday, I resolved to mention the issue of substitution procedure with my assessor today, 15 minutes before kick off. (I didn't want to be caught out as a few on here have alluded to). I simply asked him that today, since I only had CAR's on the line, it was a cup match with a 2pm kick off, was he happy for me to just physically check all players (including subs) kit prior to the match in the usual manner and then be done with it?
I pointed out to him that with each team permitted 3 subs, if I was to hold up play, annotate my notebook, jog over to the touchline, check kit, jog back into position and then restart play each time, then precious time might be eaten into, particularly if the match went to extra time & pens, and that failing light might then be an issue.
He raised his eyebrows at first but then just smiled and said, "Yep, no worries, makes sense today. Just so long as everything else during the procedure is as per the LOTG."
My assessment went quite well. One or two points (obviously) but he reassured me I had nothing to worry about.
So, thanks to a simple and tentative question asked by a young level 9 on this forum and me reading it, I was able to head off a potential down-marking during my final 6-5 assessment today.
So, thank you fellow members, and thank you Ben. You're never too old to learn something.
True story that.
