OPI in football stands for offensive pass interference , a penalty called on an offensive player for illegally hindering a defender’s chance to play the ball on a forward pass.

What OPI Means

Offensive pass interference happens when a receiver or other eligible offensive player interferes with a defender more than one yard beyond the line of scrimmage on a passing play. The key idea is that the offensive player cannot gain an unfair advantage by physically impeding the defender’s ability to cover or intercept the pass.

Common Examples

Typical actions that lead to an OPI flag include:

  • Pushing off a defender to create separation just before the ball arrives.
  • Running into or “picking” a defender who is covering a teammate, to free that teammate.
  • Blocking a defender more than one yard downfield before the pass is thrown on a play with a forward pass.

Penalty Yardage

In the NFL, OPI is usually a 10‑yard penalty from the previous spot and the down is replayed. In high school rules (NFHS), it is commonly a 15‑yard penalty from the previous spot, also with the down repeated.

Why It Matters

The rule exists to keep the passing game fair so defenders have a legitimate chance to cover receivers and play the ball. Controversial OPI calls often become big talking points online, especially when they erase long gains or late-game touchdowns.
