I would agree with your assessment that it does not have to result in an injury to be a slam. I questioned myself because I felt I should have made the call right away and didn't. And then, not making it right away, I felt that it was too late to make the slam call after we stopped to determine if there was an injury and the wrestlers caoch was screaming at me that it was a slam. Thus, my post. I admit I was just too wishy washy and should have just made the call after I had replayed it in mind that it was, in fact, a slam.
Side note - I also think two of the three timeouts are correct. Officials timeout to assess and then recovery timeout if it is due to the slam.

Thanks for the input folks.
