Shea Theodore's injury during the Four Nations Face-Off dramatically affects Canada's defense. Coach Jon Cooper confirmed that Theodore suffered a wrist injury after a hit from Adrian Kempe. Despite his limited time on the ice, the impact of his absence is significant, as the team struggles with just five defensemen. Cale Makar and Devon Toews had to log heavy minutes, with Makar exceeding 28 minutes of ice time. Meanwhile, Travis Sanheim is expected to step in as Theodore’s replacement.
