SECTION 22 GOALTENDING
Goaltending occurs when a player touches the ball during a field-goal try or tap while it is in its downward flight entirely above the basket ring level and has the possibility of entering the basket in flight, or an opponent of the free thrower touches the ball outside the cylinder during a free-throw attempt.

If it hits the backboard and is on its way down, the answer is no.
