If you are asking what is a sack in the NFL, the short answer is: it is a play where a potential passer is stopped at or behind the line of scrimmage during an apparent attempt to pass, before completing a forward pass. A tackle in the backfield is not automatically a sack; the play’s purpose matters too.

The key test: was the player trying to pass?
For a sack, the passer must still be behind or at the line of scrimmage when the play ends. The important distinction is an apparent passing attempt: the NFL scoring guidance considers the passer’s intent as well as where the play stops. A recent sack explainer summarizes that distinction and cites the NFL Guide for Statisticians.
A designed quarterback run that ends behind the line is generally recorded as a rushing play for negative yardage, not as a sack. By contrast, if a quarterback drops back looking to pass and a defender brings him down before a forward pass is completed, the play can be scored as a sack. The result may look similar on video; the play call and action help determine the statistic.
Sack or tackle for loss?
Both terms involve a play ending behind the line of scrimmage, but sack is the pass-play-specific label. A tackle for loss can also describe a runner being stopped behind the line on a running play. The NFL’s Week 3 recap reports sacks, tackles for loss, and quarterback hits as separate statistics, which helps explain why a backfield stop is not always a sack.
A defender can also hurry a quarterback without taking him down. If the passer gets the ball away before being stopped, the play is not a sack. The term refers to the pass play ending behind the line, not simply to pressure or contact.
How a sack changes down and distance
A sack uses the down that was underway and moves the next line of scrimmage back by the lost yards. For example, imagine second-and-eight from the offense’s 30-yard line. If a quarterback is brought down at the 23 before completing a pass, the play loses seven yards; the next situation is third-and-15 from the 23.
A sack by itself does not change possession or mean a penalty was called. If the passer loses the ball, whether possession changes depends on who recovers it.

NFL sack FAQ
Is every tackle of a quarterback a sack?
No. A tackle on a designed run is generally a rushing play. A sack requires an apparent attempt to pass that ends at or behind the line of scrimmage before a forward pass is completed.
Does a sack count as a tackle for loss?
A sack is a specific type of negative pass play. A tackle for loss can also happen on a run. NFL reporting lists the statistics separately, so check the box-score labels rather than assuming every lost-yardage play is a sack.
Does a sack automatically cause a turnover?
No. A sack alone does not change possession. If the ball comes loose, possession depends on which team recovers it.
The takeaway
When you see a quarterback stopped behind the line, ask two things: was he making an apparent attempt to pass, and did the play end before a forward pass was completed? Those clues explain why some losses are recorded as NFL sacks while other backfield tackles are not.
