In the NFL, an ineligible offensive player generally may not have his entire body more than one yard beyond the line of scrimmage before a legal forward pass is thrown. The foul costs five yards from the previous spot. The player does not need to touch the ball.

An ineligible receiver downfield penalty occurs when, on a scrimmage play with a legal forward pass, an ineligible offensive player has his entire body more than one yard beyond the line of scrimmage before the pass is thrown.

Eligibility, location, timing and contact all matter. A replay showing a lineman downfield at some point is not enough by itself.

Who is ineligible?

Interior linemen are the most common examples, but formation can also cover an otherwise eligible receiver. A tight end on the line becomes an interior player if another on line receiver is outside him.

Reporting as eligible addresses the numbering requirement; it does not override the need to occupy an eligible position. Numbers 50 through 79 and 90 through 99 normally require a report before their wearer can participate from an eligible position.

The quarterback directly behind the center also has specific eligibility restrictions. Treat this as an eligibility rule, not merely a rule for guards and tackles.

The whole body and the release

Picture a line one yard beyond the original line of scrimmage. The basic restriction concerns the player's entire body beyond that limit before the pass is released, not just a hand or helmet crossing it.

After release, ineligible players may advance subject to the separate restrictions on downfield contact before the pass is touched. Getting the pass away does not authorize every block.

The continuous contact exception

An ineligible player may initiate legal contact during his initial charge within one yard of the line and move farther downfield while legally blocking or being blocked. If he breaks that contact beyond the limit, he may remain stationary, move laterally or retreat before the throw. He may not simply continue advancing toward the opponent's goal.

That makes the full sequence important. A blocker two yards downfield could be protected by the contact exception, while another who disengaged and climbed there early could be illegal.

Why RPOs test the timing

On an RPO, the line can be executing run action while the quarterback decides whether to throw. A delayed decision may let a blocker advance beyond the allowance. The offense needs coordinated timing, not merely an open receiver.

A screen caught behind the line has no blanket exemption from this NFL rule. The location of the completion does not erase the player's early advance. College uses a different downfield allowance, so the rules should not be mixed.
