All of those absences were deemed "precautionary" by Team USA head coach Mike Sullivan, as was the decision to keep Brady Tkachuk off the ice during the second and third periods M

Brady Tkachuk left Monday's loss to Sweden with his brother, Matthew, already absent. Auston Matthews and Charlie McAvoy are also out.

The Americans recognized the opportunity they lost at the 4 Nations Face-Off, but will be strong next year in Italy.

This little mid-season tournament proved to be something much greater, and the NHL must now deal with the ramifications.

Team USA and Team Canada, Boston Bruins defenseman Charlie McAvoy threw a monster hit on Connor McDavid while in the defensive zone. Just 30 seconds after, Jake Guentzel scored for Team USA to tie the game up at 1-1.

McAvoy and Tkachuk did not participate in morning skate for Team USA, which already secured a spot in Thursday's TD Garden final vs. Canada, but Matthews was scratched close to puck drop. Brady Tkachuk was then lost for the night after a first-period collision.

According to the Boston Globe, Charlie McAvoy was admitted to Mass. General Hospital due to injury from play in the 4 Nations Face-Off.

Introduced as a “special guest” by Team USA head coach (and his father in-law) Mike Sullivan, McAvoy — sporting a sling on his right arm — earned a round of applause from his teammates after entering the room.
