A quarterback can make the right read, deliver a catchable pass—and still watch the other team run away with the ball. That sudden change is an interception, one of American football’s biggest momentum swings and a play that can turn a promising drive into an immediate scoring chance for the defense.
What is an interception?
An interception happens when a defensive player catches a forward pass thrown by the offense before the ball touches the ground. The catch ends the passing play and changes possession: the defending team becomes the offense, while the team that threw the pass must try to stop the return.
Interceptions are often called picks. If the defender returns one all the way for a touchdown, it is commonly called a pick-six: six points for the defense, with the chance to add an extra point or two-point conversion afterward.
A pass can be intercepted anywhere on the field, including behind the line of scrimmage, as long as it is a forward pass. A backward pass caught by the defense is treated as a fumble recovery, not an interception.
How the play unfolds
Once a defender secures the ball, they can attempt to run it toward the opposite end zone. The play ends when the runner is ruled down, goes out of bounds, scores, or another stoppage applies under the competition’s rules. The new offense then starts its drive from where the return ends, unless a score or a special rule changes the result.
For example, suppose a quarterback throws toward a receiver near midfield, but a safety reads the route and catches the ball. The safety can turn upfield while the quarterback and other offensive players try to make the tackle. If the safety is brought down at the opponent’s 30-yard line, his team takes over there with a chance to score.
Not every ball that changes hands is an interception. If the pass hits the turf before anyone catches it, it is incomplete. If a receiver catches the pass and then loses the ball, the play may be ruled a fumble instead. And if a defender knocks the pass away but nobody catches it, that is a pass breakup—not an interception.
What makes a catch an interception?
The defender must establish control of the ball in bounds. The details of what counts as an in-bounds catch vary by league: for example, NFL and college rules differ on how many feet or body parts must land in bounds. Rules can also differ over what a player must do to complete a catch while going to the ground.
A deflection does not prevent an interception. If a pass bounces off a receiver’s hands, a teammate, or a defender and another defensive player catches it before it hits the ground, the result is still an interception. These scramble catches can be difficult to anticipate because the ball may change direction suddenly.
Why interceptions happen
Some interceptions come from a quarterback’s mistake: misreading coverage, throwing late, or failing to see a defender in the passing lane. Others are down to the defense. A cornerback may disguise whether they are playing man or zone coverage, while a safety rotates toward the target just before the snap or after the ball is thrown.
Defenders also study routes and tendencies. If a receiver repeatedly runs the same pattern from a particular formation, a cornerback might recognize the setup and break toward the spot before the pass arrives. On other plays, pressure forces the quarterback to throw quickly or off balance, giving a defender more time to close in.
The offense has ways to reduce the risk. A quarterback can check the defense before the snap, move through progressions rather than locking onto one receiver, and throw the ball away when the play has broken down. Receivers can help by finishing routes and protecting the ball through the catch. None of these choices eliminates risk, but they can make a dangerous throw less likely.
Why an interception matters
An interception does more than end a drive. It gives the opponent possession and can hand it a short route to the end zone. A pick-six is especially damaging because the defense scores without its offense needing to take the field first.
Field position matters, too. An interception returned deep into the opponent’s territory may create an excellent scoring opportunity. One caught near the defender’s own end zone may still be a major defensive play, but the return team has farther to go and may choose to secure the ball rather than risk a long run.
Interceptions are recorded as a quarterback statistic, but the result is rarely the quarterback’s responsibility alone. A receiver may run the wrong route, a pass may deflect off a teammate, or a defender may simply make an outstanding play. When judging what happened, look at the coverage, the pressure, the route and the throw—not just the box score.
Interception vs. pass breakup
| Play | What happens | Result |
|---|---|---|
| Interception | A defender catches the forward pass in bounds before it hits the ground. | Possession changes; the defender may return the ball. |
| Pass breakup | A defender touches or knocks down the pass, but nobody catches it. | The pass is incomplete; the offense keeps possession for its next down. |
| Fumble recovery | A player gains possession after a ball carrier loses control of the ball. | Possession may change, but the play is not recorded as an interception. |

Frequently Asked Questions
Can a defensive player score after an interception?
Yes. The defender can return the ball for a touchdown, producing a pick-six. If the defender is tackled before scoring, the team still takes possession at the end of the return.
Does a tipped pass count as an interception?
It does if a defensive player catches the tipped forward pass before it touches the ground and completes the catch under the applicable league rules. If the ball falls incomplete, it is not an interception.
Can a pass intercepted behind the line of scrimmage count?
Yes. The key distinction is whether the ball is a forward pass, not where it is caught. A backward pass that is caught by the defense is generally ruled a fumble recovery instead.
Who gets charged with an interception?
The quarterback who threw the intercepted pass is generally credited with an interception in the statistics. That record does not necessarily mean the quarterback alone caused it; the play may involve a tipped ball, a route error or a defender’s exceptional read.
Final Thoughts
An interception is a defensive catch that ends a forward pass and hands possession to the other team. It may come from a poor decision, a disrupted throw or a defender anticipating the play—and the return can quickly turn a defensive stop into points. When one happens, pay attention to how the ball reached the defender and where the return ends; both details help explain the real impact of the play.
