Dakota,
I'm not sure where this is going...

FWIW, here is what I would do.

After the sub was given to me and (before I accepted it) I noticed it would be illegal, I would inform the coach that the substitution would be illegal - he can't do it.
I can't imagine him insisting I make the substitution, BUT if she did, I'd accept it. record it, announce it.

Then when I put the ball in play, I'd have to stop play and enforce the illegal player penalty.

I can't imagine it getting to that, but, that's all I can figure to do.
