Removing a shirt

[Clark Kent]

I'm not 100% sure on this rule, and I lost my rule book so I am hoping that one of you can help me verify this.

A player from team A has blood on his shirt and the official walks him over to the coach and tells the coach that he needs to take care of it. Before the official or the coach say anything, one of the kids on the bench jumps up and rips of his shirt, an then the player with blood takes his off and they exchange jerseys.

My question is if that is a Technical "by the book" and if so does anyone have a reference? Also how many of you enforce that and T the kid up, even though the coach didn't tell the kid to do that?

Thanks

Yes, it is a player technical foul. 10-3-6h

And it is intended to apply in a situation when a jersey must be changed due to blood per a comment from the NFHS when the rule was put in.

I've seen it enforced, and I seen it ignored.

When multiple team members offends in this manner there is an NFHS interp saying to only assess one team tech.
