From your description it is unclear if the C had a whistle. For the C to have an opinion on the play he needs to have a whistle. If he didn't blow there nothing he should be doing nothing other than assuming his new position for the throw-in.

I'm going to pull up the game on Synergy when it is available. If there was a screen developing near the division line, the Center needs to stop and officiate the match-up. He would be the primary on a double whistle, but with no whistle we don't go to our partners giving our opinions on what should be called.
