Any time you lift a guy, are responsible for his safe return. Nowadays, with guys going directly into granbys or dive thrus, etc, on returns you could say maybe the kid put himself in that position. But technically, its not supposed to matter, its still on the offensive wrestler. I would say it was unfortunate, but it was the correct call. Of course slams on the collegiate level are much different and much more is allowed,.but on the hs and down levels, you got to call those things. also, i know when i officiate anytime a kid lifts his opponent and i am "easy, easy" making sure the kid is aware of the situation.
I know both kids involved in the match. Both are good wrestlers and good kids. Sucks all around.
