An NFL catch requires control, an inbounds landing, and a football act or enough time.

Ruleset and competition covered

This page applies the 2026 Official Playing Rules of the National Football League, which the NFL states are in effect for its 2026 season and apply across its preseason, regular season and postseason. The principal provisions are Rule 3, Section 2, Article 7 (player possession); Rule 8, Section 1, Articles 3–4 (completed, intercepted and incomplete forward passes); Rule 11, Section 2 (touchdowns); and Rule 15 (instant replay).

The NFL's published 2026 changes amend Rules 6 and 19, not the catch provisions. College football is compared separately below using the NCAA materials effective for the 2026 season. NFHS high-school, Canadian, youth and flag football are outside the rulings on this page and require their own appointed code.

The three requirements are sequential

NFL Rule 8-1-3 requires all three of these steps:

1. Control: secure the live ball with the hands or arms before it touches the ground.
2. Inbounds: while in control, touch the ground inbounds with both feet or with any part of the body other than the hands.
3. Time or action: after the first two requirements, clearly extend the ball, take an additional step, tuck it and turn upfield, avoid or ward off an opponent, or perform another act common to the game. An actual act is unnecessary if the player maintains control long enough to perform one.

The third requirement begins only after control and the inbounds landing. That is why two feet down can still be followed by an incompletion. The same test governs a defender's interception; merely touching or batting the pass does not establish possession.

The ground may touch the ball, but it cannot create control

The ball does not have to be motionless. Rule 8-1-3 Note 1 says movement does not automatically mean control was lost. The question is whether the player continued to control the ball with the hands or arms.

A ball may touch the ground after the player has secured it if that control is maintained during and after the contact; Rule 3-2-7 Note 1 permits that result, provided the other possession requirements are met. The opposite sequence is not a catch: if the ball hits the ground before control exists, the ground cannot be used to trap or secure it. Visible movement matters as evidence, but movement by itself is not the rule.

Both feet, one qualifying body part, and the whole foot

The NFL's normal sideline requirement is two feet inbounds. One knee, shin, hip, shoulder, back or other body part apart from the hands also satisfies Rule 8-1-3(b); it does not take two knees or two elbows. A hand alone does not count.

Rule 8-1-3 Note 6 controls close footwork. If any part of a foot touches out of bounds during the normal continuous motion of a heel-to-toe or toe-to-heel step, that foot is out. A toe drag is inbounds, and a delayed heel-to-toe or toe-to-heel contact is treated differently from one continuous step. The receiver must still satisfy control and the third, time-or-action requirement.

Incomplete pass or fumble depends on when possession was completed

If a player has control and the required inbounds contact but has not yet completed the third requirement, Rule 8-1-3 Note 2 applies when the player hits the ground. There is no possession if the player loses control and the ball touches the ground before control is regained, or if the player regains control out of bounds.

If all three requirements were completed first, a later loss in the field of play is a fumble under Rule 8, Section 7, unless another dead-ball rule has already ended the down. “Survive the ground” is therefore shorthand, not a separate fourth test: it describes what is required when ground contact occurs before the catch process has finished.

The catch must be completed before the touchdown exists

The same Rule 8-1-3 process applies in the end zone. A catch completed while the player is inbounds and any part of the ball is on, above or behind the opponent's goal line is a touchdown under Rule 11-2-1, and the ball is then dead. A receiver does not have to take the ball back into the field of play.

Crossing the goal-line plane with a loose or uncontrolled pass is not enough. If the player is still completing the catch and loses control under the ground-contact rule, the result is an incomplete pass, not a touchdown. By contrast, once the catch in the opponent's end zone is complete, a later loss cannot turn that score into a fumble.

Simultaneous possession and being carried out

• Simultaneous catch: under Rule 8-1-3 Note 4, if two eligible opponents gain control simultaneously and both retain it, the ball belongs to the passing team. It is not simultaneous if one player controls it first and the opponent later gains joint control.
• Held up and carried out: Note 5 awards a completed or intercepted pass when a player in control is held up and carried out by an opponent before getting both feet or another qualifying body part down inbounds. The player need not retain control on landing out of bounds. The note requires the player to be held up and carried out; ordinary contact that merely affects where the player lands does not by itself satisfy it.
• Defenseless receiver: Note 3 treats a receiver as defenseless throughout the catch process and until capable of avoiding or warding off impending contact. Whether the pass is caught and whether contact violates Rule 12-2-9 are separate decisions; an incomplete pass does not erase an otherwise enforceable personal foul.

Incomplete touching and illegal touching are different rulings

Rule 8-1-4(c) says the pass is incomplete, with no illegal-touching foul, if a player who has been out of bounds is the first to touch it before reestablishing inbounds with both feet or another body part apart from the hands.

A different provision applies after an originally eligible offensive receiver has reestablished. Under Rule 8-1-8(b), if that receiver previously went out voluntarily or was legally forced out and then first touches or catches the pass, it is illegal touching: loss of down at the previous spot, and a caught ball remains live. Rule 8-1-5(e) supplies the important exception: a receiver forced out by an opponent's foul may regain eligibility by attempting to return immediately and reestablishing inbounds before touching the pass.

Outcome when the catch process fails

Under Rule 8-1-4, an incomplete forward pass is dead immediately, counts as a down, and returns the ball to the previous spot. This is the result when the Rule 8-1-3 catch process is not completed or the pass goes out of bounds, subject to any accepted foul or another specific rule that changes enforcement.

“Loss of down” here means the attempted down is used; it is not the additional loss-of-down penalty attached to some fouls. If the offense threw on first down and the pass is simply incomplete, the next play is normally second down at the previous spot.

How to analyze an NFL catch ruling

1. Identify the code first: this path is for the 2026 NFL rules, not NCAA or high-school football.
2. Was the player eligible and inbounds, and was the ball still a live pass that had not already touched the ground or gone out of bounds?
3. Did the player secure control with the hands or arms before any ground contact by the ball?
4. While controlling it, did the player get both feet or one non-hand body part down inbounds? Apply the continuous-step and toe-drag note.
5. After those events, did the player clearly perform a football act or maintain control long enough to do one?
6. If ground contact occurred before step 5, was control retained or regained before the ball touched the ground and, at the sideline, while still inbounds?
7. Check the special provisions: simultaneous catch, carried out of bounds, prior out-of-bounds status, touchdown, or a separate foul.
8. Apply the result: complete pass or interception, incomplete pass, touchdown, or—if possession had already been completed—a possible fumble.

Six NFL 2026 hypotheticals

These are constructed examples applying the cited rules, not NFL casebook plays or descriptions of real games.

• Two-foot sideline catch: the receiver controls the pass, plants the first foot inbounds, drags the second toe inbounds, then tucks the ball before touching the sideline. Ruling: complete. Decisive fact: both feet and the football act followed control.
• Continuous heel-to-toe step: the receiver controls the pass, but during the normal motion of the second step the heel lands inbounds and the toe lands on the sideline. Ruling: incomplete. Decisive fact: Note 6 makes the entire second foot out of bounds.
• Ball brushes the turf: the receiver controls the pass before it reaches the ground, satisfies the landing and time requirements, and keeps control while the ball touches the turf. Ruling: complete. Decisive fact: control existed before, during and after ground contact.
• Loss while still completing the catch: the receiver controls the ball and lands with both feet, but before any football act or enough time elapses, falls and loses control; the ball hits the ground. Ruling: incomplete. Decisive fact: Rule 8-1-3(c) was not completed before the loss.
• Catch, then loose ball: the receiver controls the ball, gets both feet down, tucks and turns upfield, then a defender knocks it out before the runner is down. Ruling: catch and fumble. Decisive fact: all three possession requirements were complete before the loss.
• Carried across the boundary: an airborne receiver controls the pass and an opponent holds the receiver up and carries the receiver out before any foot or body part lands inbounds. Ruling: complete under Note 5. Decisive fact: the rule expressly awards possession in this held-up-and-carried-out situation.

What replay can change

Pass completion is reviewable under NFL Rule 15-3-2. A coach may challenge a reviewable ruling when Rule 15-1 permits; only the Replay Official or the NFL officiating designee may initiate review after the two-minute warning, in overtime, on scoring plays and in the other situations listed in Rule 15-1-2. Rule 15-2-1 requires clear and obvious video evidence to change the field ruling.

If replay changes an incompletion to a catch, Rule 15-3-2 places the ball at its location when the receiver's second foot or qualifying body part touched the ground with control, with no advance awarded. If replay instead establishes a catch and subsequent fumble, the rule can award the ball to a clear recovery in the immediate continuing action. Replay therefore decides more than “catch or no catch”; the field ruling can limit the reconstructed advance.

College football does not use the NFL two-foot rule

For the 2026 NCAA season, the NCAA site publishes the 2025 Football Rules Book as the base text, supplemented by its changes effective for 2026 and its May 2026 Instant Replay Casebook. None of the 2026 amendments changes the catch definition in NCAA Rule 2-4-3.

The NCAA also uses control, an inbounds contact and a time-or-action element, but its boundary test is materially different: Rule 2-4-3 requires any part of the body to touch inbounds. The NCAA's 2026 replay guidance expressly includes a hand, foot or knee as examples. Thus one foot—or even another single body part—can satisfy the NCAA location requirement, while the NFL requires both feet or one body part other than the hands. The NCAA also expressly requires complete and continuous control through ground contact when a player goes to the ground in the act of catching. Do not transfer the NFL boundary test to an NCAA game.

Short answers to frequent arguments

• “Two feet means catch.” Not by itself in the NFL; control and the third requirement are still missing.
• “The ball moved, so it is incomplete.” Movement is evidence, not an automatic loss of control.
• “The ball touched the ground, so it is incomplete.” Not if control existed first and was maintained through the contact.
• “The offense and defense use different catch tests.” They do not; a defender must complete possession to make an interception.
• “NFL and college sideline catches are the same.” They are not: the NFL normally requires two feet, while NCAA Rule 2-4-3 accepts any body part down inbounds.
• “Any first touch after going out is merely incomplete.” Only touching before reestablishment has that no-foul result; an eligible offensive receiver who returns inbounds may instead commit illegal touching under Rule 8-1-8.
