Vegas Golden Knights defenseman Shea Theodore will miss the remainder of the 4 Nations Face-Off after sustaining an upper-body injury while playing for Canada.

The Knights announced Thursday that Theodore is week-to-week, one day after he was pushed into the glass on a hit by Sweden's Adrian Kempe in the second period of Canada's 4-3 overtime victory.

Philadelphia Flyers defenseman Travis Sanheim will draw in to replace Theodore in the lineup for Canada. Sanheim was a healthy scratch on Wednesday.

Theodore, 29, has 48 points (seven goals, 41 assists) and averages 22:03 of ice time in 55 games for the Knights this season.

A Stanley Cup winner with Vegas, Theodore has 354 points (78 goals, 276 assists) in 552 career games with the Anaheim Ducks and Golden Knights.
