10.3.3 SIT. B and 9-1
 

I'm a little baffled by the reference to 9-1 at the end of 10.3.3.B. 9-1 is about free throw violations. Could it be a misprint and really be referring to 9-11, which is the BI violation rule?

10.3.3 SITUATION B: A1 jumps for a try near the basket but loses his/her balance after releasing the ball. A1 grasps the basket to prevent injury. The ball: (a)is; or (b) is not, in the basket or on the ring while A1 is hanging on the ring.
RULING: In (a), it is basket interference by A1 which causes the ball to become dead and no goal can be scored. In (b), there is no violation unless A1 is still hanging on the ring when the ball touches the basket or goes into the basket. In both (a) and (b), A1’s grasping is not penalized if it is judged there was a possibility of injury had he/she not grasped the basket. (9-1)

Out of curiousity, what is 9-1?

BITS
I think it actually is referring to itself in the 10.3.3 Exception:

A player may grasp the basket to prevent injury

The reference may be, as you say, for 9.11 and apply to the entire comment, not just the last sentence, but I can't say why they would reference a free-throw violation section (9.1) at all.
