5 to 4 to 5 Players

[SteveF]

Okay a couple of questions for you all.

1. If a team has 5 players eligible to play do they have to have 5 on the floor? I want the actual rule not just oppinion here. I was at a game once where the coach did not sub when subs were available and a kid fouled out. Later on he made the substitution and they were back to 5 players.

2. If a team has only 5 players and one is injured to the extent that he is not able to be bought in with a time out. That player must leave the game and can not sub until after the clock has started and the next oppurtunity to sub comes around. So his team will have to play with 4 until that time when he can come back in and make it 5, correct?
