(#33) arrives late
 

Situation:
High school rules:
Red coach has a player (#33) arrive late that was never put into the book. Just before half time, coach says he wants to put # 33 into the game starting the third quarter. Beginning the third quarter, coach has #33 put into the book, but does not start him on the court. Two minutes into the third quarter, #33 comes into the game.
When does the 'T' get charged?
When put into the book?
Or when entering the court?

When his name was put into the Scorebook.

MTD, Sr.

I can't find it. Could site a rule # or case play?
Thanks
