Illegal substitution question

[Warrenkicker]

mikesears is exactly right. If you have the illustrated book it shows almost exactly your example on page 81. It is illegal to use a substitution situation to deceive the opponents at or immediately before the snap. By running the player toward the sideline like he was being replaced then you are using that as a deception. The goal of football is to deceive the opponent as to who has the ball and where it is going. Not who is playing.
