The center circle, represented in the diagram by a blue circle overlapping a white circle, is located at the midpoint of the center line and has a radius of ten yards, as highlighted by the red line with an arrow. This circle serves two key purposes: first, it is used for kick-offs to start the game or restart it after a goal. During a kick-off, the ball must be placed inside the circle, and all players except the player taking the kick must remain outside of it. Second, the circle plays a role in penalty kicks, where only the kicker and goalkeeper are permitted within the center circle.

The midfield is marked by a center circle with a radius of 10 yards, centered on the halfway line.
