An NFL Spike Is Legal Only Right After The Snap. A Delayed One Is Grounding.
The spike is the one legal way to throw the ball straight into the ground, and the NFL rulebook keeps its window narrow.
Throwing the ball directly into the ground is intentional grounding in the NFL, even with no pass rusher near the quarterback. The spike is the exception.
The legal spike
A T-Formation Quarterback is permitted to stop the game clock legally to conserve time if, immediately upon receiving the snap, he begins a continuous throwing motion and throws the ball directly into the ground.
Rule 3 defines a T-formation quarterback as a player aligned one yard or less behind the snapper.
What turns it into grounding
- 01A delayed spike, after holding the ball for strategic purposes
- 02More than one quick step backward before the spike
- 03Spiking to take time off a clock that is already stopped
The cost
Intentional grounding is loss of down and 10 yards from the previous spot, and after the two-minute warning it can also bring a 10-second runoff. A legal spike is still an incomplete pass, so it uses a down.
Quick answers
- Is spiking the ball intentional grounding in the NFL?
- Not if the quarterback receives the snap aligned one yard or less behind the center and immediately throws it directly into the ground to stop the clock. A delayed spike is grounding.
- Can an NFL quarterback take a step back before spiking the ball?
- One quick step back is allowed. More than one is intentional grounding.
- Can a quarterback spike the ball to run time off the clock?
- No. A quarterback can only spike the ball to stop a running clock. Spiking to take time off is intentional grounding with a 10-second runoff.
