A defensive back can play perfect coverage for several seconds, reach the receiver at the right moment, and knock the football away before a catch is completed.
The stat sheet may record that play as a PBU. While covering player performance and defensive trends, I have seen this abbreviation confuse newer fans because broadcasts rarely stop to explain it.
So, what is PBU in football, and why does the number matter?
PBU stands for pass breakup, a defensive statistic credited when a player directly prevents a completed forward pass.
This guide explains how officials record PBUs, which defenders earn them, and how they differ from interceptions, passes defended, drops, and penalties.
Quick Answer: What Is PBU in Football?
PBU stands for pass breakup, sometimes written as pass broken up. It is a defensive statistic recorded when a player directly disrupts a forward pass, resulting in an incompletion.
The defender may swat the football away, deflect it, tip it, or knock it loose before the receiver completes the catch.
Unlike an interception, the defender does not gain possession of the ball. Cornerbacks and safeties record the most PBUs because their main responsibility involves covering receivers.
However, linebackers and defensive linemen can also receive credit for disrupting passes. A PBU is important because it shows that the defender affected the passing play.
However, it should not be treated as the only measure of strong coverage.
What Happens During a Pass Breakup?
A pass breakup follows a clear sequence from the moment the quarterback throws the football until the play is ruled incomplete.
- Quarterback Throws the Pass: The quarterback releases a forward pass toward an eligible receiver running a designated route.
- Defender Maintains Coverage: The defender stays in position to challenge the catch while avoiding illegal contact that could result in a penalty.
- Ball Reaches the Catch Point: The football arrives at the spot where the receiver attempts to secure the catch, and the defender makes a play on the ball.
- Defender Breaks Up the Pass: The defender swats, tips, or knocks the football away before the receiver completes the catch.
- Pass is Ruled Incomplete: Because the receiver fails to establish possession, the play is ruled incomplete.
- PBU is Recorded: If the defender directly caused the incompletion, the official scorer credits that player with one pass breakup (PBU).
Common Ways Defenders Record a PBU

Defenders use several legal techniques to stop completed passes. The proper method often depends on body position, route depth, and ball placement.
1. Swatting the Ball Away
A defender may extend one hand and strike the football before it reaches the intended receiver. This technique works best when the defender can clearly track the pass but lacks enough time or position to attempt a safe interception.
A firm, well-timed swat prevents the catch while helping the defender maintain balance and stay ready to make a tackle.
Coaches often encourage this decision because forcing a difficult interception attempt may allow the receiver to secure the ball and gain several additional yards.
2. Playing Through the Receiver’s Hands
When a defender cannot turn around to track the football, the receiver’s eyes and hands provide important clues about its arrival.
As the receiver raises both hands to secure the pass, the defender reaches between or through them, knocking the ball away before possession is established.
This technique, commonly called playing through the hands, requires precise timing and controlled movement.
Reaching too early or making unnecessary body contact may prevent a fair catch attempt and result in a defensive pass interference penalty.
3. Deflecting the Pass
A defender may extend one hand into the passing lane and slightly redirect the football before it reaches the intended receiver.
Even minor contact can change the ball’s path enough to prevent a clean catch or force the receiver to adjust too late.
This type of deflection commonly occurs on slant routes, crossing patterns, and other short throws where the ball arrives quickly.
Good positioning and fast reactions help the defender disrupt the pass without making unnecessary contact with the receiver.
4. Knocking the Ball Loose at the Catch Point
A receiver may get both hands on the football but still fail to complete the catch. Before possession is fully established, the defender can strike or punch the ball loose at the catch point.
This technique requires strong timing because the defender must target the football without making illegal contact.
When the ball comes free before the receiver maintains control and completes the required catching process, officials may rule the pass incomplete.
The defender can then receive credit for a pass breakup.
5. Tipping a Pass at the Line of Scrimmage
Defensive linemen and linebackers can earn PBUs by reading the quarterback’s throwing motion and raising their arms into the passing lane.
This technique helps them disrupt the play without reaching the quarterback or recording a sack.
Even a slight touch can redirect the football enough to stop a clean completion.
A tipped pass may fall safely to the ground, or it can remain in the air long enough for another defender to intercept and force a turnover.
Which Players Usually Earn PBUs?
Pass breakups are most common among defensive backs, although several positions can record them during passing plays.
| Defensive Position | How the Player Records PBUs |
|---|---|
| Cornerbacks | Cover outside routes, deep passes, and sideline throws |
| Safeties | Defend deep zones, crossing routes, and middle passes |
| Nickel Defenders | Cover slot receivers on short and intermediate routes |
| Linebackers | Disrupt throws to running backs and tight ends |
| Defensive Linemen | The tip passes near the line of scrimmage |
How PBU Differs from Interceptions and Passes Defended?
A PBU, interception, and pass defended all relate to stopping a completed pass, but each term describes a different result.
A PBU results in an incomplete pass, so the offense usually keeps possession for the next down. An interception gives the defense possession and ends the offensive series unless a penalty changes the ruling.
Defenders are often taught to knock the ball away when an interception attempt is too risky.
A controlled swat can prevent a deep completion, while a missed interception attempt may leave the receiver open for a large gain.
A pass defended, commonly listed as PD, is a broader statistic. It may include both pass breakups and interceptions.
Passes Defended = Pass Breakups + Interceptions
Does Every Incomplete Pass Count as a PBU?
Not every incomplete pass results in a PBU, because the defender must directly contribute to the failed catch.
| Usually Counts as a PBU | Usually Does Not Count as a PBU |
|---|---|
| Defender knocks the ball away before the catch | The quarterback throws the ball too high or wide |
| Defender tips the pass and causes an incompletion | Receiver drops the ball without defensive contact |
| Defender dislodges the ball before possession | The quarterback intentionally throws the ball away |
| Defender legally reaches through the receiver’s hands | Pass lands near no eligible receiver |
| Defensive lineman bats the pass at the line | The quarterback releases an inaccurate pass under pressure |
| Defender directly prevents the completed catch | A penalty cancels the defensive result |
How Is a PBU Recorded on the Stat Sheet?
Official scorers review each play to identify the defender who most directly caused the incompletion. In many cases, the decision is simple because one player clearly touches the football or knocks it away.
Other plays require more judgment, especially when two defenders arrive together, or several players contact the receiver.
Scorer usually awards the PBU to the primary defender who prevents the catch. Replay footage can help determine who touched the ball first or caused it to come loose.
Team statisticians, league scorers, and independent analytics services may occasionally record the play differently.
A PBU appears as an individual defensive statistic, and season totals are commonly listed beside interceptions, tackles, forced fumbles, sacks, and other defensive performance measures.
Why PBUs Matter for Defensive Players?
PBUs help show how consistently a defender challenges passes and influences the outcome of passing plays.
- Coverage Ability: A defender must remain close enough to contest the pass at the catch point.
- Reaction Time: The player needs to respond quickly after the quarterback releases the ball.
- Timing: Reaching too early can cause a penalty, while reaching too late allows the catch.
- Ball Awareness: Strong defenders can locate the football while maintaining coverage responsibility.
- Drive Prevention: A breakup may stop a first down, touchdown, or major gain.
- Third-Down Value: PBUs on third down can force punts and end offensive possessions.
- Red-Zone Impact: Breaking up a pass near the goal line can prevent an immediate touchdown.
Are More PBUs Always Better?
A high PBU total can show that a defender consistently challenges passes and prevents completions, but the number needs proper context.
A cornerback may record many PBUs because quarterbacks repeatedly target that side of the field, creating more chances to make plays and suggesting that offenses feel comfortable testing the coverage.
Another cornerback may finish with fewer PBUs because receivers rarely gain separation and quarterbacks avoid throwing in that direction.
When I evaluate defensive performance, I also consider allowed targets, allowed completion percentage, allowed interceptions, allowed touchdowns, allowed defensive penalties, missed tackles, yards allowed per target, opponent quality, and coverage assignments.
PBUs are most meaningful when reviewed with game film and overall performance data.
When Can a PBU Become Pass Interference?
A legal pass breakup becomes defensive pass interference when a defender restricts the receiver before the football arrives.
- Common examples include grabbing the jersey, holding an arm, pushing before the catch attempt, blocking the receiver’s path without playing the ball, making early body contact, or preventing both hands from reaching the pass.
- Defenders may legally challenge the football, but they cannot unfairly remove the receiver’s opportunity to make a catch.
- Turning toward the ball can support a legal play, yet it does not excuse holding, grabbing, or premature contact.
Rules differ across the NFL, college football, and youth leagues, but the standard remains consistent: the defender must time the challenge correctly and avoid restricting a receiver before the ball arrives.

How Do Coaches Evaluate PBUs?
Coaches judge pass breakups by reviewing the assignment, technique, and game situation surrounding each play.
- Pre-Snap Alignment: Coaches check whether the defender started in the correct position for the assigned coverage.
- Route and Coverage Call: The receiver’s route and defensive assignment help show how difficult the play was.
- Defender’s Leverage: Proper inside or outside positioning can limit the receiver’s space and catching angle.
- Quarterback Accuracy: A poor throw may make the breakup easier than the final statistic suggests.
- Breakup Timing: The defender must attack the football without arriving early or committing a penalty.
- Down and Field Position: A third-down or red-zone PBU may carry greater value than a routine breakup.
- Technique and Penalty Control: Coaches review whether the defender used sound technique and avoided illegal contact.

Conclusion
Knowing what PBU is in football makes defensive stat lines much easier to understand. A pass breakup occurs when a defender directly prevents a completed forward pass without catching the ball.
Cornerbacks and safeties earn most PBUs, although linebackers and linemen can also record them.
The statistic can highlight strong timing, close coverage, and awareness at the catch point. Still, I never judge a defender by PBU totals alone.
Targets, interceptions, penalties, touchdowns allowed, and game film provide essential context.
The next time a defender reaches across a receiver and knocks the football away, check the stat sheet afterward.
Frequently Asked Questions
Can a Linebacker Get a PBU?
Yes. A linebacker can earn a PBU by deflecting a pass, covering a tight end, or disrupting a throw intended for a running back.
Does a Dropped Pass Count as a PBU?
A normal receiver drop does not usually count. The defender must directly contribute to the incompletion by touching the ball or disrupting the catch.
Can Two Defenders Receive Credit for One PBU?
Most stat providers credit the primary defender responsible for the incompletion. However, scoring methods can differ between teams, leagues, and analytics services.
Is a Tipped Pass Always Recorded as a PBU?
Not always. The defender’s touch must directly contribute to the incompletion, and the official scorer must determine that the action affected the play.
