3rd and 6 on team A’s 20 yd. line. The ball is snapped and A1 throws a legal forward pass caught by A2, who advances to the B 36 yd. line. After the play, the officials realize that B had 12 men on the field.[/b]

Once in a while, there are situations where officials have difficulty completing the count because of late substitutions, etc. Otherwise. I agree with the others. Game officials should catch this before the play.

The 12th man is B12 who (a) was on the field at the snap, but realized it shortly after and left the field at his team box, never participating in the play

In this case, we have illegal participation because he didn't try to leave until after the snap.

Part of Casebook play 3.7.1b comment reads, " However, if the official’s count is not completed before the snap is imminent or if the substitution has not been monitored, it becomes illegal participation at the snap if more than 11 are in the formation. Each team is responsible for substituting legally and for replaced players to leave immediately as required."

Give A the choice of 1) 15 yards from the previous spot or 2) the results of the play.



However, if he tries to leave before the snap, we have illegal substitution (a non-player foul). All non-player fouls are enforced from the succeeding spot.

(b) remained on the field during the play, although he just stood there

Same thing. Illegal participation. Live ball foul at the snap. Give A same choices as above.

(c) entered the field after the snap because he thought his team only had 10 players on the field. What is the foul and enforcement?

This year, this is illegal participation. 15 yards from the basic spot or the results of the play.
