In American football, a dimeback is a cornerback or safety who serves as the sixth defensive back (fourth cornerback or third safety) on defense. The third cornerback on defense is known as a nickelback. The dimeback position is essentially relegated to backup cornerbacks and safeties who do not play starting cornerback or safety positions. Dimebacks are usually fast players because they must be able to keep up on passing plays with 3+ wide receivers.
Dimebacks are brought into the game when the defense uses a "Dime" formation, which uses six defensive backs rather than four or five. Usually, a dimeback replaces a linebacker in order to gain better pass defense, although some teams may substitute the extra defensive back for a defensive lineman in their dime formation.
