injury coach on the floor

[lpbreeze]

3.3.5

here is the question
A-1 is injured and the coach is beckoned onto the floor to attend to A-1. A-1 is okay and coach decides to leave him in the game, Official charges team A with a time out. Is the official correct?
I would say no because the Coach has to request it first or A-1 has to leave the game. It sounds like the ref is just calling one to allow the player to stay in the game.
