CHICAGO -- Blackhawks captain Jonathan Toews announced Sunday that he is dealing with symptoms of long COVID-19 and chronic immune response syndrome.
Toews, 34, hasn't played since Jan. 28. The Blackhawks placed the center on injured reserve Wednesday with what they said was a non-COVID-19-related illness.
"It has been really challenging to play through these symptoms," Toews said in a statement released by the team. "In the last few weeks, it has reached the point where I had no choice but to step back and concentrate on getting healthy. I am thankful for the patience and support of my teammates, the coaching staff, and the entire Blackhawks organization."
Toews missed the 2020-21 season with what he described as chronic immune response syndrome.
He has spent his entire career with Chicago, winning three Stanley Cup titles. He is eligible for free agency after this season.
Blackhawks general manager Kyle Davidson told ESPN's Emily Kaplan on Sunday that with the uncertainty over Toews' health, he will not be traded. The trade deadline is March 3 at 3 p.m. ET.
"We're going to work with him and support him in whatever he needs to make sure he's feeling good and feeling strong and in a spot where he can come back on the ice," Davidson told reporters. "We'll take it day by day, but the hope is that he can still play some games here down the stretch.''
Toews had 12 goals and 25 assists in 71 games when he returned to action last year, and he had looked stronger this season. He has 14 goals and 14 assists in 46 games for the Blackhawks.
"We feel for him and just supporting him right now,'' coach Luke Richardson said. "He was back this week, first steps of getting back and working out and skating, and unfortunately he wasn't getting the results that he wanted.''
