3rd Lane space?

[BillyMac]

On free throws, there is a maximum of two offensive players and four defensive players in the six marked lane spaces. The defense must be in the first marked lane spaces, above the neutral zone marks, on all free throws. The offense must not occupy the first marked lane spaces, above the neutral zone marks. The shooter and all the players in the designated lane spaces must wait until the ball hits rim or backboard before entering the lane. Players, other than the shooter, and the players in the designated lane spaces, are to remain behind the free throw line extended and behind the three point arc, and may not penetrate the free throw line extended and the three point arc until the ball hits rim or backboard. During a free throw, no opponent, including bench personnel, may disconcert the free thrower. For free throws when there are no rebounders in the marked lane spaces, i.e. technical fouls, the nine nonshooters shall remain behind the free throw line extended and behind the three point arc.
