Hossa, who had 1,134 points (525 goals, 609 assists) in 1,309 NHL games and won the Stanley Cup with the Blackhawks in 2010, 2013 and 2015, did not play this season because of a progressive skin disorder and side effects of medication to treat it. He was placed on long-term injured reserve Oct. 4.
Hossa said last June he had been undergoing treatment for the disorder under the supervision of the Blackhawks medical staff for the past few years but the side effects and his reaction to them made it impossible for him to play.
He said Saturday that's still the case.
"Before the season, the NHL sent me to a clinic in Minneapolis to see a specialist who confirmed that it's impossible to play hockey when using those [anti-allergic] medicaments," Hossa told the newspaper. "I have to be aware of what might happen and I don't want to get back to the state I had been in during the previous seasons."
His last game was April 20, 2017, when the Blackhawks lost 4-1 to the Nashville Predators in Game 4 of the Western Conference First Round of the Stanley Cup Playoffs.
"Since then, I haven't [put the hockey equipment on]. Not even a single time," he said. "I've been on the ice couple of times just to skate with my daughters but I haven't had my hockey gear on."
Hossa said he and his family will return home to Slovakia.
"The daughter goes to school for another school year so we had to make a decision," he said.
Blackhawks general manager Stan Bowman said in April that Hossa's condition hadn't changed and that there was "no indication he's going to play next year, either."
