Sub for player with blood

[crosscountry55]

I think it's too late, but I don't have a book in front of me.

If I'm directing A3 to leave the game and before he sends a sub to the table, Coach A says, "Can I call a timeout instead?", then sure, if the problem can be corrected before the end of the timeout, A3 can stay in.

However, after said direction, once A6 reports and is beckoned, now A3 has been replaced and time must run off the clock before A3 can re-enter, regardless of whether Team A takes a timeout or not.
