Thank God I found this thread.
As most of you will have guessed I'm not only new to the site but am new to refing.
I had my first game yesterday, and was asked, "Ref this is OK isn't it", the guy and his colleague had full grip both front and back of the jumpers shorts. Sh!t here's a test, went through my mind, no I said no pre gripping!
But we did that all last season, I don't care says me, you can have your hands slipped loosely under the short, but the rules are NO PRE GRIP and NO LIFTING supports fine.
Now this is at level 10 and it was a third team friendly!
OK clear enough well when it comes to the game, and remember it's my first, GOD how many can you look at in a second

!, so it isn't until the second half I notice neither side is loosely placing hands under shorts but both sides are gripping, I let it go for the remainder of the match as the players during the match had been supported and lowered safely, but I could not tell if even though they had pre-griped if they were lifting or not.
This has been playing on my mind so sorry to resurrect this thread just needed to get that off my chest.
