Neutral zone infraction
Penalty: Defense
What it is
A defender moves into the neutral zone before the snap and causes an offensive player to react, such as flinching or jumping.
The penalty
The penalty is 5 yards, and the down is replayed. The penalty is enforced from the line of scrimmage.
More detail
Defenders use quick fake moves to bait the offense into a false start. If the offensive player moves because of that, it is this foul on the defense, not a false start on the offense.
Animated play
Blue circles are the team with the ball. X marks the other team. The yellow oval is the ball.
- The two lines are set, and the space between them is the neutral zone.
- A defender moves into it and an offensive player flinches. Without the defender’s move, this would have looked like a false start.
- The officials call neutral zone infraction on the defense: five yards, and the down is replayed.
