Don't talk to my player

[iref4him]

I am working a rival game last night and two players who are playing hard and with great intensity. Both were getting a little aggitated. So during the dead ball period, I told them to start playing basketabll and stop with the looks at each other and continue to play hard. Just keep it under control. BOth of them nodded their heads and shook hands. The home coach goes off and starts yelling at me for talking to his player. He calls a time out and walks out towards me letting me know his displeasure for talking to his player. He continues to come towards me. I walk away to the other side of the court. He stands there staring at me. He wants an answer to his question. He went into the huddle to talk to his team. At the end of the time out, I walk over and let him know I am just keeping both players under control and left it at that. Question? Would you have talk to him during the time out or wait or just let it go?
