Concerns about Canadian coronavirus restrictions could push hockey south of the 49th parallel into the U.S. this summer. Seven of the 10 locations the NHL has zeroed in on to hold playoff games if it resumes are American cities not restricted by Canada’s 14-day mandatory quarantine upon arrival. As 24 teams figure out how to squeeze an expanded roster and limited personnel into one of two “hub” cities, the Vancouver Canucks are even considering relocating training camp to the U.S. if the situation doesn’t change in the coming weeks. The NHL is expected to choose its game cities in the next three to four weeks.
