This is something, if you get a chance, you might be able to get taken care of in pregame. If when watching warm ups there are variations of formations that are illegal address it with the coach and describe to him the rule (if neccessary) so he either has a back or a person on the line, not both. I have found that 100% of the time coaches are very receptive to this and appreciate this "preventive officiating".
Not a rule reference, but when officiating anything we can address in this manner I think everyone is better off.
