释义 |
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. Were it not for this rule, the quarterback could easily turn the sack into an incomplete pass which, by rule, would advance the ball back to the line of scrimmage and stop the clock. HistoryThe 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.

Intentional grounding is called only if all of the following components are present:

PenaltyThe penalty for intentional grounding has several components so that the offense gains no benefit from the violation:[4]
