Another substitution question
 

It's the period between the third and the fourth quarters. The second horn to signal players back on the floor has sounded.

Just after the horn sounds, Coach A wants to make substitutions. He is informed that he cannot, since the rules state he must have his players in place before the first horn.

Can the coach call a timeout to "buy" the substitutions?

I'll answer by asking these questions:

Is it allowable to call a time-out at that point in the game?

If not, why?

If so, what are the rules regarding subs and time-outs?

Don't have my books in front of me, so I'm going to take a blind stab at this from memory and say that a timeout is allowed in between quarters and any overtime period, and that a sub must report before the first warning horn of the timeout.

Am I to assume from the silence that I'm right?

Yes, a sub who reports after the warning horn must only wait for the next opportunity to sub.

Had a player go down after getting fouled on a fast break. Shooting foul. Coach came out to check on the player. He then got annoyed when I told him I'd either need a sub for the shooter or he could use a timeout to keep her in the game.

Not sure what he wanted me to do -- set aside the rule just for him?
