Would need to see the video for confirmation, but based on past guidance (and lots of it) we should have a flag for a substitution infraction. Guidance has consistently told us that there may be no use of the substitution process in any form to gain an advantage. This sounds like a coached and orchestrated play to make it look like a legitimate substitution in process where the kick is not imminent and use that to K's advantage. Without the sideline (non-player) participation, this should be OK.
