Change of mind on substitution?

[OmniSpiker]

Could I get clarification for this (NCAA) ?

Does the Ump/R2 need to recognize the sub before authorization for substitution or nearly the scorekeeper making the appropriate changes?

If the R2 doesn't recognize the sub and ther players exchange, R2 should call them back, execute the sub while informing them that further exchanges without recognition would result in UD and a refusal to allow the sub.

I assume you meant "TDW."

Thanks, you are correct.
