When I was listening to a Sirius NHL broadcast this morning, as they were going through the recap and highlights, they mentioned that a player had gotten a goal that was marked unassisted, as he got his own rebound off the goal post and subsequently scored. (I believe it was Kyle Clifford of the Kings vs the Vegas Golden Nights on 2/27/18, but unsure.)
They were surprised that it was recorded unassisted, and as I understand the rules of hockey, if a player gets his own rebound from a shot blocked by the goalie and scores, the assist(s) go to the last one or two players to touch the puck in a contributing manner.
I looked at some assist rules and clarifications on the web, but I can't find anything that would suggest that should have been an unassisted goal. Is there a case for this, or was the recording of an unassisted goal in error?
