The puck was under Ersberg and behind the glove. Then he hit him on the glove and the puck went in. Dont think it should have been a goal, dont now what the rulebook says but its too late anyway. Go Sweden!
I believe the IIHF rules say that as long as the puck is deemed loose within the crease, if the puck is knocked in, the goal will be allowed. I haven't seen the play but if the ref had a clear view of the puck and could see that it was still in play and that the goalie had no real hold on the puck to deem the play frozen, the goal will count. If not, then it definitely isn't a goal. Again, I haven't seen the play for myself but that's the closest thing to a rule that I saw that was related to the situation described here.
