There is a "Defensive 3-second" violation in the NBA. No defensive player is allowed to remain in the lane for 3 seconds without "actively guarding" an offensive player. (I forget what the exact definition of "actively guarding" is.) This rule is in effect when the offensive team has team control in its frontcourt.

The penalty is a non-unsportsmanlike technical foul against the defensive team. (It doesn't count toward the player's six fouls or toward the bonus.) The offensive team is awarded one FT. The offensive team then retains possession with the unexpired time on the 24-second clock or with 14 seconds on the 24-second clock, whichever is greater.
