Server tosses ball - hits rim

[pavbref]

I can't find a NHFS rule or case explanation of this situation, but in the NCAA rulebook there is the following:

13.1.3.2 After being clearly released or tossed from the hand(s) of the server, the ball must be cleanly hit for service. If the service toss contacts any obstruction before contact of the service, the serving team loses the rally.

The USAV rulebook states the following:

12.6.1.2: It is a serving fault if the service toss touches any obstruction before the service contact.

Hope this is helpful.
