A doctor from British Columbia, Dr. Harjas Grewal, provided his thoughts, saying that it is likely a separated shoulder. Of course, that is without him being able to fully assess Greig and just going off of the clip. He did say that depending on the severity of the separation, Greig could play in the semi-final or the final, should Canada make it that far. If the severity is lower grade he would be able to play with tape/support and pain management.
