Howden (upper body) is expected to be out for a while after being stretched off the ice against the Predators on Thursday, per NHL.com.
While Howden was released from the hospital and appears to have avoided any neck or spinal damage, the 23-year-old center is still set to miss a chunk of time. In his last five outings, the Calgary native registered one goal, three shots and 10 hits while averaging 10:38 of ice time. Pavel Dorofeyev figures to get an extended look at the NHL level with Howden sidelined.
