In American football, a position on the defense team assigned to cover the receiver positioned deep down the field, typically considered the second-most important defensive position after the cornerback. The slot is a difficult position to play well because it requires the player to have excellent athletic ability, because they must be able to cover fast receivers at all times and stay with them when they run routes and change directions. In addition, they must also be able to play press coverage and off-man coverage at the same time.
