Question re: Jurisdiction

[Raymond]

Thanks Jurassic for jinxing me.

I'm trail tableside. Lead calls team control foul on Red12. As I get ready to head downcourt to be new Lead table gets my attention and informs me Red12 has 5 fouls. I start my procedure: signal "5" to partners, inform coach (sub is already up and headed towards table with warm-up top on), tell table to start countdown, turn to inform player (he is already on the bench). When I turn back to wave in sub there is a young man standing there with red shorts and a white tank top on. Before I can say a word he steps on the court. Crowd starts laughing. He had pulled his jersey off with his warm-up top and didn't realize it.

I, of course, did not T him up. Had him get his warm-up top off the floor and get his jersey out from it.
