Mittelstadt (upper body) is a game-time call for Thursday's contest against Ottawa, Mike Harrington of The Buffalo News reports.
Coach Don Granato said a Mittelstadt return Thursday is "possible," Harrington adds. The 23-year-old has played in just six games since the end of November, averaging 15:07 of ice time -- 3:06 during the power play -- and tallying two points over that period.
