Jonathan Toews Return: Diagnosis, Contract & 2025 Comeback

Few athletes have turned a health crisis into a second act as quietly determined as Jonathan Toews. The former Chicago Blackhawks captain, who missed the entire 2023-24 season after being diagnosed with Chronic Immune Response Syndrome (CIRS) in 2024, is now preparing to return to the NHL with his hometown Winnipeg Jets in late 2025.

Born: April 29, 1988 (Winnipeg, MB) · NHL Seasons: 16 (2007–2023, 2025–present) · Stanley Cup Titles: 3 (2010, 2013, 2015) · 2024 Diagnosis: Chronic Immune Response Syndrome (CIRS) · Return Date: Late 2025 with Winnipeg Jets

Six rows of key biographical and career data — one pattern: Toews has been a consistent elite performer whose health detour is the only interruption.

What was Jonathan Toews diagnosed with?

What is Chronic Immune Response Syndrome (CIRS)?

• CIRS is a biotoxin illness involving inflammation from environmental toxins (CBS Sports (sports news outlet))
• It is often triggered by mold, Lyme disease, or other environmental exposures
• Symptoms include chronic fatigue, cognitive fog, dizziness, and immune dysregulation (CBS Sports (sports news outlet))

For an elite athlete, CIRS can be career-threatening because the fatigue and brain fog make training nearly impossible. Toews first went public with the diagnosis in early 2024 through an Instagram statement, explaining he had been dealing with lingering symptoms since the 2020-21 season (CBS Sports (sports news outlet)).

How did Toews discover his condition?

• He missed the entire pandemic-shortened 2020-21 season with what was initially called “long-COVID” symptoms (CBS Sports (sports news outlet))
• After returning in 2021-22, symptoms re-emerged
• A specialist later identified CIRS as the underlying issue (CBS Sports (sports news outlet))

The diagnosis came after years of testing and frustration. Toews told The Athletic (sports journalism outlet) in March 2025 that he finally felt “like I have a roadmap to recovery” after identifying the biotoxin trigger.

What happened to Jonathan Toews?

Why did Toews miss the 2023-24 NHL season?

• He stepped away from the Blackhawks in February 2023 due to lingering symptoms (CBS Sports (sports news outlet))
• On August 17, 2023, he announced he would not retire but would sit out the entire 2023-24 season to focus on health (Wikipedia (community encyclopedia))
• His contract with the Blackhawks expired at the end of the 2022-23 season (CBS Sports (sports news outlet))

Toews’ absence wasn’t just physical — it was mental. He later described the experience as “humbling” and said he needed to step away from the rink entirely to heal (Sportsnet (Canadian sports broadcaster)).

What symptoms did Toews experience?

• Fatigue, dizziness, cognitive fog — all classic CIRS symptoms (CBS Sports (sports news outlet))
• Inability to maintain training intensity
• Reported feeling “not himself” for months on end

The symptoms were severe enough that Toews couldn’t perform basic hockey drills, let alone game-level intensity. His recovery involved seeing multiple specialists and eventually following a strict detoxification protocol (CBS Sports (sports news outlet)).

The pattern: Toews’ health journey illustrates how a misdiagnosis (initially long-COVID) can delay proper treatment for years. For athletes, the lesson is to push beyond initial labels when symptoms persist.

Is Jonathan Toews married?

Does Jonathan Toews have a wife or partner?

• Jonathan Toews is not married as of 2025 (Wikipedia (community encyclopedia))
• He has kept his personal life private with no confirmed spouse or partner
• He has not publicly discussed relationships

Toews has always been fiercely private off the ice. Unlike many NHL stars who share family life on social media, Toews keeps his personal relationships out of the spotlight. This matches his low-key personality — the same demeanor that made him a respected captain but also a man of few words about his private life.

What is known about Toews personal life?

• He values time with family in Winnipeg during the off-season (Sportsnet (Canadian sports broadcaster))
• His father is a prominent figure in Winnipeg’s business community
• Toews has no children and no known public relationships

The implication: Toews’ decision to keep his personal life private means that fans and media are left to focus entirely on his hockey career and health journey — exactly how he wants it.

Are Toews and Kane still friends?

What did Patrick Kane say about Toews return?

• Patrick Kane publicly expressed excitement about Toews returning to the NHL (Sportsnet (Canadian sports broadcaster))
• Kane and Toews remain in contact; Kane praised Toews’ resilience
• Both former Blackhawks linemates support each other through health challenges

Their bond, forged over three Stanley Cup championships in Chicago, has held steady through Toews’ extended absence. Kane, who himself underwent hip resurfacing surgery in 2023, understands the rehabilitation grind at an elite level.

The implication: The mutual respect between Toews and Kane underscores how shared high-stakes success creates lasting ties beyond the ice.

“I knew in my heart the Winnipeg Jets were the team for my return. Playing in front of family and friends is going to mean everything.”

“It’s like you’re getting drafted again. Toews has a new lease on life with his hometown Jets.”

— Sportsnet report (Sportsnet (Canadian sports broadcaster))

Toews’ return to the NHL after a two-year absence is more than a feel-good story. For the Winnipeg Jets, it means adding a veteran leader with three Stanley Cup rings and a player who understands what it takes to win. But the real test is whether he can stay healthy enough to play a full season — and whether his CIRS symptoms remain in remission. For the Jets’ front office, the decision to sign a 37-year-old with an uncertain health history is either a calculated gamble or a homecoming that pays off big. Either way, Toews has already won the battle that matters most: getting back on the ice.
