I’m not an NFL rules expert by any means. But my understanding is that the Lions’ #68 was positioned on the end of the line as a left tackle, went downfield at the snap, and caught a pass in the end zone for an apparent 2 pt conversion. After discussion, the crew flagged him for illegal touching, which wiped out the 2 pts. Under NFL rules, any player not wearing a number 1-49 or 80-99, must report to the officials that he is assuming a position that makes him an eligible receiver, i.e., in the backfield or on the end of the line. If he fails to so report, he remains ineligible because of his number even if he lines up in an eligible position. When he is the first to touch a forward pass, the touching is illegal, which results in a 5 yd. penalty from the previous spot and replay of the down.
It might be appropriate to ask the Lions’ coach why, after the penalty was enforced, he didn’t then kick the try and go to OT, rather than put the game on the line with what was essentially “4th & goal” from the 7 yd. line, having already used up the trick play they were counting on to win the game.
I understand there is video that some people are using to question whether #68 may have actually reported and the crew missed it. I expect the NFL to make some sort of statement about that once they’ve heard from the crew.
