Quinn Hughes prepared to join U.S. 4 Nations roster, may replace injured D-man McAvoy [Video]

Quinn Hughes is on standby for the United States at the 4 Nations Face-Off.

Whether the Vancouver Canucks captain gets into Thursday’s final against Canada remains to be seen.

The Boston Bruins announced star defenceman Charlie McAvoy will miss the championship game after being admitted to hospital for tests related to an upper-body injury suffered at the tournament.

American head coach Mike Sullivan said Tuesday at TD Garden that Hughes — last season’s Norris Trophy winner as the NHL’s top blueliner — was en route to Boston.

But as of Tuesday Hughes was still in Vancouver, skating with the Canucks in a red no-contact jersey.

Among six players initially named to the U.S. roster back in June, the 25-year-old missed Vancouver’s final four games ahead of the 4 Nations and was replaced by Jake Sanderson of the Ottawa Senators.
