Horse-collar tackle explained: the NFL’s 15-yard collar-and-yank foul

When a defender reaches inside a runner’s collar and yanks him down from behind, the play often looks like a routine tackle until the runner’s legs buckle and a yellow flag flies. That is the horse-collar tackle — a 15-yard personal foul under Rule 12, Section 2, Article 16 of the 2026 Official Playing Rules.

What the rule bans

Article 16 says no player shall:

• grab the inside collar of the back or the side of the shoulder pads or jersey, or
• grab the jersey at the name plate or above,

and pull the runner toward the ground.

Two details matter on every close call:

• If the runner’s knees are buckled by the action, it is a foul even if he is not pulled completely to the ground.
• The grab has to be of the inside collar (pads or jersey) or of the jersey at or above the name plate. A fistful of jersey below the name plate, without the collar, is not this foul by itself.

The pocket and close-line exception

The horse-collar rule does not apply to a runner who is:

• in the pocket area, or
• in the area defined by close-line play.

The pocket area is the space between the outside edges of the normal tackle positions, extending back to the offensive end line. Close-line play is contact in that pocket on the offensive side of the line of scrimmage and within three yards on the defensive side. In plain terms: a defender who collars a quarterback still in the pocket, or a runner tangled up at the line, is not automatically flagged for a horse-collar the way an open-field yank is.

Penalty and signal

Horse-collar tackle: loss of 15 yards and an automatic first down. The signal abbreviation on the broadcast graphics is usually HC.

Can replay take the flag off?

Yes, in a narrow case. Under the replay rules, a horse-collar flag can be picked up if there is clear and obvious video evidence that the defender did not contact the inside collar of the back or side of the opponent’s shoulder pads or jersey with the hand, and did not contact the jersey at the name plate or above with the hand. Replay is checking the grab location, not re-litigating whether the pull looked hard.

How the rule got here

Owners banned the open-field horse-collar for the 2005 season after a 27-5 vote. The competition committee tied the change to 2004 injuries, including serious lower-leg damage on plays by Dallas safety Roy Williams — the rule was widely nicknamed the Roy Williams Rule. Early language left room to collar a quarterback in the pocket and to grab jersey rather than the pad collar.

In 2006 the definition expanded to include grabbing the inside collar of the jersey, not only the shoulder pads. In 2016 it expanded again: pulling a runner down by grabbing the jersey at the name plate or above became illegal even without an inside-collar grip. That is the version still in Article 16 today.

What to watch for on the next flag

• Where are the hands? Inside the collar, or on the name plate / numbers high on the chest?
• Did the knees buckle? The runner does not have to hit the ground for it to be a foul.
• Is it open field? Pocket and close-line plays are carved out.
• Was it a facemask instead? Twisting or pulling the facemask is a separate 15-yard foul (12-2-15), with possible disqualification if flagrant.
