The St. Louis Blues are facing a significant setback as top defenseman Colton Parayko is set to miss the remainder of the regular season due to a left knee injury sustained during a recent shootout victory against the Los Angeles Kings. Blues general manager Doug Armstrong announced that Parayko will undergo knee surgery and will be evaluated in six weeks. With Parayko averaging nearly 24 minutes of ice time per game and contributing 35 points this season, his absence is expected to have a substantial impact on the Blues' playoff hopes, especially as they trail just one point behind the final wild-card spot in the Western Conference.
