FIBA Substitutions

[Cleefy]

Hi All,

Just after some clarification to a situation that occurred in our local competition on Friday night.

Team A has no substitutes sitting on their bench, and is playing on the court with 5 players. Coach requests that we sub one of their players off onto the bench so that he can talk to him.

I believe this is not allowed, as it places the opposing team at a disadvantage (by resting on of their players)... however my partner makes the decision that this can happen.

I am aware that a substitution can only be requested by a player, so the coaches request should have been denied anyway, but my partner overlooked this...

Can anyone clarify whether this sub is allowed or not, overlooking Article 19.3.1?
