Betting Out of Turn--What is the Ruling?

[EasilyFound]

This came up in my home tourney game.

We are three handed.

UTG raises 1000. I go all-in. While player C is thinking, UTG says, "I call." Player C says, "I'm still thinking." Then the dealer (another player who busted out but is dealing for us) asks if UTG is compelled to call. We ruled that UTG is compelled to call and cannot raise if Player C calls. Player C calls and UTG calls. UTG ane Player C are not all-in, so they play the hand while I watch.

Did we do this correctly?
