Midway through the second period in a home game versus Seattle, as the Avalanche forward was swiping at a loose puck, contact was made with the Kraken's Jamie Oleksiak who was coming from the opposite direction.
The subsequent collision saw the 6-foot-7 Seattle defenseman connect with more force on top of Lehkonen's right shoulder which forced the Avalanche player's momentum down headfirst and towards the end boards, where his helmet would first make contact.
