A fifth defensive back (in addition to two cornerbacks and two safeties) who is deployed for additional pass coverage.
"The coach decided to shift a nickelback into the secondary to provide extra support against the opposing team's three-receiver formation."
In plain English: A nickelback is a person who listens to and enjoys music from Nickelback, a popular Canadian rock band known for their catchy but often criticized songs.
"They are huge fans of Nickelback and played their songs at every party this summer."
Usage: Use this term in American football contexts to describe the extra defensive player added specifically for deep pass coverage when a team needs more help against long throws. It refers strictly to that specific roster position rather than any other type of backup or substitute on defense.
The term "nickelback" is a blend of "nickel" and "cornerback," modeled after the similar-sounding "quarterback." It was coined because the player serves as the fifth defensive back on the field, linking his position to the five-cent American coin.
