Gustafsson signed a two-year, entry-level contract with the Blackhawks on Thursday, ESPN Chicago reports. The 23-year-old spent the past season with Frolunda in the Swedish Hockey League, producing four goals and 29 points over 55 games. Gustafsson, a former fourth-round draft pick of the Oilers in 2012, will more than likely spend most of the 2015-16 campaign at AHL Rockford, but his left-handedness could result in him seeing some ice time with the parent club.
