Lodged ball.

I'm thinking wrong rim and backboard here.

I also think everyone is reading way too far into the "overhead equipment" rule in 7-1-2d. The rule does not mention overhead equipment 'being used in the game' (as some have suggested), so it applies to all overhead equipment equally and without restriction.
