Pietrangelo delivered a strong, yet solid, hit on Semin early in the game that left the Canes forward on the ice for several minutes while trainers spoke with him.
Here's the hit in question:
Semin finally made his way to the locker room and didn't return to the game. The Hurricanes confirmed he had an upper-body injury during the third period. Considering how long he remained on the ice and the severity of both the hit and fall, you'd have to assume he suffered a concussion. However, the Hurricanes aren't releasing any specifics yet.
Semin has just three goals and nine points through 19 games this season.
