Blues say Walker is out long term and trade Alexandrov to the Kings for Thomas

The St. Louis Blues will be without the services of another forward for an extended period of time. Nathan Walker is expected to miss at least eight weeks with what the team called an upper-body injury. Rookie Jimmy Snuggerud is out six weeks to recover from surgery on his left wrist. Alexey Toropchenko is considered week to week after sustaining burns to his legs in a home accident. St. Louis on Tuesday also made a trade of minor league forwards, sending Nikita Alexandrov to Los Angeles for Akil Thomas.
