1.noun
Definition

a defensive player in American football who joins the four usual defensive backs when a team chooses to use an extra player to cover the pass — the formation is called the nickel defence because five defensive backs are on the field, like a five-cent coin has the value of five cents.

Example

The Seahawks used a nickelback to cover the opponent's third wide receiver on a pass play.

nickelback used against extra wide receiver

Ravi practised as a nickelback all week because the opponent often threw on third down.

Usage Note

The nickelback is not a separate position in the standard defence — it is usually an extra cornerback who replaces a linebacker when the team expects a pass play. The name comes from the nickel formation (five defensive backs), which was named after the five-cent US coin.

Common Mistakes

The nickelback plays behind the quarterback.
The nickelback plays in the defensive backfield, usually covering slot receivers.
The quarterback is on offence, not defence.

Sense: noun/1

A nickelback is one type of defensive back (DB) — the collective term for all pass-defending players in the secondary. The two main DB roles are cornerback (covers wide receivers on the outside of the field) and safety (plays deeper and provides last-line defence against runs and long passes). A nickelback is essentially an extra cornerback who comes onto the field in the nickel formation (five DBs total). While a standard defence fields two cornerbacks and two safeties, the nickelback adds a fifth DB — usually replacing a linebacker — to better defend against passing plays. The nickelback typically covers the slot receiver (the receiver lined up between the offensive line and the wide receiver). A linebacker, by contrast, plays closer to the line of scrimmage and focuses on stopping the run or rushing the quarterback. So when a team faces a pass-heavy offence, the coach might sub out a linebacker and bring in a nickelback for better pass coverage.

Etymology

English

The term 'nickelback' comes from American football's 'nickel defence', first used by the Philadelphia Eagles in the 1960s. The nickel defence puts five defensive backs on the field instead of the usual four. The name was chosen because the nickel (a five-cent US coin) represents the number five — just as a dime defence uses six defensive backs (a dime is a ten-cent coin). The word 'back' refers to the player's position in the defensive backfield.
