"I'm sure everything's going to come down to that moment, but I'll surprise myself," Hossa said Wednesday.
He'll find out when his No. 81 is raised to the rafters by the Blackhawks before they play the Pittsburgh Penguins on Sunday (7 p.m. ET; SN, NBCSCH, ATTSN-PT, ESPN+).
The forward will be the eighth player to have his number retired by the Blackhawks, joining goalies Glenn Hall (No. 1) and Tony Esposito (No. 35), defensemen Pierre Pilote and Keith Magnuson (each No. 3), and forwards Bobby Hull (No. 9), Denis Savard (No. 18) and Stan Mikita (No. 21).
Hossa had 1,134 points (525 goals, 609 assists) in 1,309 games with the Ottawa Senators, Atlanta Thrashers, Pittsburgh Penguins, Detroit Red Wings and Blackhawks, including 415 points (186 goals, 229 assists) in 534 regular-season games for Chicago. He scored at least 30 goals in a season eight times and at least 40 three times. He had 149 points (52 goals, 97 assists) in 205 Stanley Cup Playoff games.
"He was a great player," Penguins forward Sidney Crosby said of Hossa, his teammate with Pittsburgh in 2007-08. "I just remember, first couple games that I played with him, he was just flying by me on the backcheck. He gets a lot of credit for how good he was offensively, but he was really good defensively too. I think, you look at his career, he was so consistent, it was great to have the opportunity to play with him."
Inducted into the Hockey Hall of Fame last November, Hossa won the Stanley Cup three times with the Blackhawks (2010, 2013 and 2015). A progressive skin disorder ended his career after the 2016-17 season.
"I put him in the same class as [former NHL defenseman] Zdeno Chara, other brilliant players, that you get to meet them and everybody says this, but it's just true: they're way better humans," Florida Panthers coach Paul Maurice said. "Just so good with the equipment guys, so good with the medical guys. When we look at professional athletes and we idolize them, and I mean that in a good way, and you get kids and you want them to look up to somebody, Marian Hossa would be the guy you'd want kids to emulate."
Hossa played the final eight seasons of his 19-year NHL career with the Blackhawks after signing a 12-year contract with them on July 1, 2009.
"You can put that into perspective by how much success or not success the team has had since he retired. He was such a big piece of the team," Blackhawks forward Patrick Kane said. "Everyone talks about his two-way play and how good that was, but he did score 500-something goals, too, so he's pretty good offensively. A great human as well. He was huge for us."
