What is the momentum rule in the NFL?

If a defender gains possession in the field of play and his original momentum carries him into his own end zone, it is not a safety. His team gets the ball where he gained possession.

Does the momentum rule apply to punts?

Yes. It covers scrimmage kicks and free kicks as well as interceptions, fumbles and backward passes.

Can the momentum call be reviewed?

No. The rulebook says a ruling on whether a player's momentum caused him to enter his end zone is not reviewable.

An NFL Interception That Carries Into The End Zone Is Not A Safety. Momentum Decides

The NFL's momentum exception gives the defense the ball at the spot of the catch when the play carries the defender into his own end zone.

Rule 11, Section 5, Article 1 of the NFL rulebook defines a safety, and Exception 2 is the momentum rule.

If a defensive player, in the field of play, intercepts a pass or catches or recovers a fumble, backward pass or kick, and his original momentum carries him into his own end zone where the ball is declared dead in his team's possession, it is not a safety.

Where the ball goes

01At the spot where his foot or other body part touched the ground to establish possession
02At the 1-yard line, if that spot is inside the 1
03A touchback, if that spot is in the end zone

When it is still a safety

The exception covers momentum, not choice. Approved Ruling 11.32 describes a defender who intercepts at his own 4, slides to a stop at the 1, then loops into the end zone to avoid a tackler and is tackled there. The ruling is a safety, because his momentum did not take him into the end zone. A live ball foul by his team in the end zone also makes it a safety.

Under Rule 15, whether a player's momentum caused him to enter his end zone is not reviewable.
