We've got 9-6-4e : "For a player to be lying on the ground to deceive opponents at or immediately before the snap or free kick" that warrants a flag

and could loosely applied to your OP...other choices could be 1-1-6 or 9-9-5...another choice would be to kill the play (as per your suggestion) and asked the "injured" player : "Sorry about your illness

, son. now you have to leave for a play

...Oh, by the way ,was this your coach's idea

?" If the answer is" yes"

under 9-8-1 ; if "no"

under 3-6-2f....it's a play that probably won't be ran again
