In a thrilling opener of the 4 Nations Face-Off, Canada edged Sweden 4-3 in overtime, thanks to Mitch Marner's winning goal. However, the victory came at a cost, as defenseman Shea Theodore suffered a wrist injury, leaving the team to compete with only five defensemen. Despite the setback, players like Nathan MacKinnon, Sidney Crosby, and Connor McDavid showcased their skills in front of a sellout crowd. The tournament features Canada, the U.S., Sweden, and Finland in a round-robin format, culminating in a championship game on February 20.
