i believe there was a slight change to the illegal participation this year, but i would like to know the final verdict on this play situation. A11 thinking he has been replaced comes off the field, then realizing he is suppose to be in the game, goes back on the field and does not get in between the numbers and the play gets off. is this illegal substitution, participation, or what? and if so, penalty(live ball?) and yardage.
