Intentional grounding in the NFL is a foul when a passer under defensive pressure throws a forward pass without a realistic chance of completion to avoid a loss of yardage. But not every throwaway is illegal. The rules distinguish a passer who remains in the pocket from one who has moved outside the tackle position, and they also recognize a legal clock-stopping spike.
This guide follows the official 2026 NFL Rulebook, Rule 8, Section 2, checked October 11, 2026. The examples focus on NFL rules; NCAA and high-school football are not interchangeable.
What makes a pass intentional grounding?
Officials look for a passer facing an imminent loss of yardage because of defensive pressure, then a pass that lacks a realistic possibility of completion. One key indicator is whether an originally eligible receiver is in the direction and vicinity of the throw. The official considers the full play: pressure, passer location, ball trajectory, receiver position and whether contact affected the throw.
The pocket exception: when can a quarterback throw it away?
If a passer is outside, or has been outside, the tackle position and the thrown forward pass reaches the line of scrimmage or beyond, the NFL has an important exception: intentional grounding ordinarily is not called even without a nearby eligible receiver. The line of scrimmage is extended beyond the sideline for this purpose, so the ball may land out of bounds if it crosses that line.
Simply stepping a few inches toward the sideline does not establish the exception. The passer must actually leave the tackle position as defined in the rule. Officials also address what happens if a loose ball leaves the tackle area before a new pass.
Can you throw the ball at a receiver’s feet?
A pass deliberately placed near an eligible receiver can be a legal incompletion when it is realistically catchable in context, even if the quarterback is under pressure. In contrast, throwing directly into an empty patch of ground from within the pocket while trying to avoid a sack is the classic grounding risk. A receiver running away at the last moment or a defender disrupting the throw may affect the judgment.
What about spiking the ball to stop the clock?
An NFL passer taking a snap under center can legally stop the clock under the specified immediate-spike procedure: the passer starts a continuous throwing motion immediately upon receiving the snap and throws the ball directly to the ground. Delay or unnecessary movement can remove the protection. Teams often use this to preserve a chance to kick a field goal near the end of a half, but a spike consumes a down.
Does contact by a defender change the ruling?
Yes. The NFL expressly accounts for certain throws materially disrupted by physical contact. When a defender significantly affects an otherwise legitimate passing motion, officials may rule no grounding even if the ball lands nowhere near its intended receiver. Contact alone is not a universal excuse; the sequence must match the relevant rule exception.
What is the NFL penalty for intentional grounding?
Grounding is a loss-of-down penalty with yardage enforcement under Rule 8. The enforcement spot depends on the precise circumstances, commonly at the pass spot (subject to the rule’s minimum-yardage provisions). A grounding foul committed in the passer’s own end zone results in a safety, awarding two points to the defending team. The exact placement is one reason a throwaway under pressure can be far more costly than an ordinary incompletion.

Five quick examples
| Play | Likely treatment |
|---|---|
| Under pressure, QB in pocket throws toward no eligible receiver | Grounding risk |
| QB leaves tackle position, throw travels beyond line of scrimmage | Common exception; normally no grounding |
| QB tries to hit eligible receiver, defender alters throw materially | Physical-contact exception may apply |
| Immediate legal spike after snap | No grounding, but down is used |
| QB grounds ball while in own end zone | Safety if grounding is called |
Frequently asked questions
Is throwing the ball out of bounds always grounding?
No. A passer outside the tackle position may throw beyond the line of scrimmage, including out of bounds, under the stated exception.
What does “outside the pocket” mean?
In common commentary it means a quarterback has left the region bounded by the offensive tackles. The official NFL definition uses tackle position, not the generic idea of taking a few scrambling steps.
Is there a receiver-distance rule in yards?
No universal five-yard or ten-yard receiver-distance threshold appears in the rule; officials evaluate whether the pass had a realistic chance of completion toward an originally eligible receiver.
Can an NFL team lose a down for grounding?
Yes. That is one of the chief differences between a legal incomplete throwaway and intentional grounding.
