Just for reference:

NBA Rule 12, Section IV - Basket Ring, Backboard, Support:

b. A defensive player who deliberately hangs on his opponent's basket ring, net, backboard or support shall be assessed an unsportsmanlike technical foul. If he touches the ball during a field goal attempt, points shall be awarded consistent with the type of shot.

EXCEPTION: An offensive or defensive player may hang on the basket ring, backboard or support to prevent an injury to himself or another player, with no technical foul assessed.

c. Should a defensive player deliberately hang on the basket ring, backboard or support to successfully touch a ball which is in possession of an opponent, an unsportsmanlike technical foul shall be assessed.

(NOTE: Section 5-c of this same rule states a technical foul called for (1) delay of game, (2) coaches box violations, (3) defensive 3-seconds, or (4) having a team total of less or more than five players when the ball is alive, or (5) an offensive player hanging on his basket ring or backboard, is not considered an act of unsportsmanlike conduct, and cannot be charged towards disqualification.)

If there is no contact, charge basket interference and put in the two or three points. The hanging on the rim is legal in this situation because of preventing injury.

This is different than FIBA's Article 49:
49.1.2 It is a technical foul when a player disregards warnings by officials or uses tactics such as . . .

Hanging on the ring in such a way that the weight of the player is supported by the ring.
In a dunking situation, a player may:
− Grasp the ring momentarily and incidentally.
− Hang on the ring if, in the judgement of the official, he is trying to prevent injury to himself or to another player.

Article 49 states it is only if it is in a dunking situation. NBA Rule 12 does not have the same.
