Prior to the 2017–18 season, the Blackhawks revealed Marian Hossa would miss the entire 2017–18 season due to a progressive skin disorder. The team made two major trades before the 2017 NHL Entry Draft; veteran defenseman Niklas Hjalmarsson was dealt to the Arizona Coyotes in exchange for Connor Murphy and Laurent Dauphin, while Artemi Panarin was traded to the Columbus Blue Jackets to reacquire Brandon Saad in a four-player deal. Both Hjalmarsson and Hossa were core members of the Blackhawks roster that won three Stanley Cups in 2010, 2013 and 2015. The team also traded goaltender Scott Darling to the Carolina Hurricanes and center Marcus Kruger to the Vegas Golden Knights, while also lost defensemen Trevor van Riemsdyk to the Golden Knights in the 2017 NHL Expansion Draft and Brian Campbell, who retired. The Blackhawks acquired wingers Patrick Sharp, Tommy Wingels and Lance Bouma in free agency.
