Ball rolling onto court

[rvietti]

I had a situation in a game last week. I am lead in a fairly small gym. The stands are close to the court and I had my back to the stands.

The shooter is on my side of the court and a ball rolls onto the court at the same time that the shooter puts up the shot. I wave off the shot (before the shot went in) and give the ball back to the team which had just shot. I also warned the benches about this happening again.

Since I did not see how the ball was launched onto the floor, I felt I could not penalize. My partner did not see the ball come on the court either.

My question is: Is this unsportmanslike conduct and a "T" and any opinions on how I handled this situation.
