The Blue Jackets have signed goaltender Shawn Hunwick to an amateur tryout contract, club Executive Vice President of Hockey Operations and GM Scott Howson announced today. Hunwick will serve as the backup to Allen York for tonight's game against the Red Wings. Steve Mason suffered an upper body injury during the morning skate and is listed as day-to-day. Hunwick, 22, just completed his senior season at the U. of Michigan, where he posted a 24-12-3 record with a 2.00 goals-against average, .925 save percentage and five shutouts.
