Substitution

[The_Rookie]

A1 and A2 are in the game and A3 is fouled..shooting 2

1) A11 replaces A2 for rebounding purposes after 1st FT

2) A3 makes 2nd FT and horn sounds for subs by Team A

3) A22 subs in before throw in

Questions:

1) Can A22 Sub for A11?

2) Can A2 Sub in or have to wait until a "tick comes off clock"?

Since A2 was in the game before clock stopped for foul and then went to bench..is that the reason why he would have to "Sit a Tick"?
