In
gridiron football, intentional grounding is a violation of the rules where "a passer...throws a forward pass without a realistic chance of completion."[1] This typically happens when a
quarterback about to be
sacked passes the ball toward an area of the field with no
eligible receiver. Without this rule, the quarterback could almost always avoid a sack by intentionally throwing an
incomplete pass (which would
stop the clock and return the ball to the line of scrimmage, avoiding any loss of yardage); instead, the penalty of intentional grounding effectively continues play as if the defense had succeeded in sacking the quarterback.
History
The rule against intentional grounding seems to date from
1914, two seasons after an
incomplete pass ceased to result in a
turnover,[2] in the period of rule experimentation that followed legalization of the
forward pass in 1906.
Elements
A ball carrier, in any location, commits intentional grounding when throwing a pass with no realistic chance of completion in order to avoid a sack; for instance, throwing the football down near himself. However, the rules explicitly allow the quarterback to
spike the ball immediately after receiving it from the center to
stop the clock[a] without using a
time out.
Intentional grounding is called only if all of the following components are present:
Imminent pressure: The passer must face "imminent loss of yardage."[1] There is no violation when the passer is not about to be tackled but the receiver simply fails to run the route the quarterback expects.
Location: In the
NFL and
college, the quarterback must be inside the
tackle box (or "pocket"), the area between the two
offensive tackles on the line. If the quarterback scrambles to either side and is closer to the sideline than that side's tackle lined up, there is no penalty. The NFL added this element of the rule in 1993 in order to protect quarterbacks;[3]high school football followed suit in 2022.[4] However, intentional grounding can be called on a quarterback (or other offensive ballcarrier) outside the pocket if the pass fails to go beyond the line of scrimmage. In the
CFL, the quarterback is not subject to an intentional grounding penalty regardless of his location, so long as the pass reaches the line of scrimmage.
Target of the pass: The ball must be passed where there is no
eligible receiver, such as well out of bounds. If a receiver is nearby but fails to catch the ball, or if a defender deflects the pass, there is no penalty. Conversely, if the pass is caught by an ineligible receiver, intentional grounding may still be called if there is no nearby eligible receiver (although a penalty of
illegal touching would also be called, forcing the defense to decide which penalty to accept, if any).
After a flag is thrown, the officials may confer to decide whether all these components were present, and may "pick up the flag" upon finding there was no intentional grounding.
Penalty
The penalty for intentional grounding has several components so that the offense gains no benefit from the violation:[5]
In the NFL, the offense is penalized 10 yards from the line of scrimmage, except in specific circumstances.[b] In college football, the ball is placed at the spot of the pass.
The offense loses the
down rather than replaying the down, as is the case for most other penalties.
If the quarterback threw the pass from his team's own
end zone, the penalty results in a
safety being scored by the defense.[6]
Like many offensive penalties, intentional grounding committed near the end of either half results in a
ten-second runoff of the game clock, if the defense desires. This ensures that intentional grounding is not an effective means of
clock management.
Pro Bowl
In the
NFLPro Bowl, intentional grounding is legal in order to make the game safer.[7]
^If the foul occurs inside the offense's own 20-yard line, then the penalty would be assessed half the distance to the goal, rather than the full 10 yards. In such a case, if the spot of the foul is within 10 yards of the line of scrimmage but is greater than half the distance to the goal, then the ball is placed at the spot of the foul, instead.
