Bruins prospect Jakub Lauko suffered what appeared to be a significant knee injury in the opening minute of the opening game of the World Junior Championship.
Lauko, 19, was skating for the host Czech Republic team when he was clipped from behind, causing him to twist his right leg as he was hit head-on by another player.
Lauko, a forward, fell to the ice and immediately clutched his leg 53 seconds into the game and on his first shift. He eventually made his way to the bench, and was seen on camera hopping on his left leg down the hallway to the team locker room.
