NCAA Jewelry question

[FMadera]

So last night I was there early, and both teams were courtside early, so I gathered everyone around (one team at a time) and had them check their jewelry, and told them any hoops/loops/etc needed to be snug to the ear, with the insides touching ear entirely (or really close). They understood, removed anything too big, and there were no issues. It was a pretty calm D3 setting, not sure if I'd do that for D1 (probably just have the coach deal with it instead).
