Are nonjumpers allowed to move onto the center restraining circle at any time?

In NFHS basketball rules, nonjumpers are required to remain outside the center restraining circle during the jump ball until the ball has been legally touched by one of the jumpers. This regulation helps to maintain order and fairness during the initial possession of the game by ensuring that the jumpers, who are specifically participating in the jump ball, have the necessary space to contest the ball without interference.

Once the ball is tossed into the air and has been legally touched by one of the jumpers, nonjumpers can then enter the circle and join the play. This rule is critical as it prevents potential disruptions or disadvantages to the jumpers at the start of the game. Therefore, until the jump ball is successfully completed, nonjumpers must wait outside the restraining circle, ensuring a level playing field right from the beginning of the game.
