Technical foul on substitute—mechanics

[bballref3966]

Let's say a Team A substitute is sitting on the bench wearing his warmup over his jersey. He says something to me that crosses the line and I call a technical foul. Obviously I have to get his number because it counts as one of his five. What is the best way to go about obtaining his number? Ask him to pull up his warmup shirt or tell the coach to ask him?

Also, what is the best way to report this to the table? Let's say his number is 12. "White, 12, technical foul. That counts as one of his five. That is also charged to the coach. Coach, by rule you must sit for the rest of the game."?

Thanks!
