The NHL offseason is officially underway, shifting the league's focus from the pursuit of the Stanley Cup to the quiet, grueling work of physical rehabilitation. For dozens of players, the summer months are defined by surgical procedures, specialized physical therapy, and strict recovery protocols.[2]
This year's offseason injury report carries a distinctly optimistic tone. Several key contributors who missed significant time—or played through agonizing pain during the postseason—have successfully undergone major surgeries and are currently on track to return for training camp in September.
Among the most notable recoveries is Philadelphia Flyers forward Owen Tippett. Tippett was a vital offensive engine for the Flyers, but his postseason performance was severely hampered by a sports hernia and an associated internal bleeding issue.
Despite the severity of the injury, Tippett managed to play through the pain during the Flyers' first-round series against the Pittsburgh Penguins. However, the internal bleeding eventually forced him out of the lineup during the subsequent series against the Carolina Hurricanes.
In early June, Tippett successfully underwent sports hernia surgery. Medical reports indicate that the internal bleeding has completely healed, removing a significant complication from his recovery process and allowing him to focus entirely on rebuilding his core strength.

The typical recovery timeline for a sports hernia repair ranges from six to twelve weeks. Both Tippett and the Flyers' medical staff have expressed high confidence that he will be fully cleared and ready to participate when training camp opens.[2]
While Tippett's outlook is clear, the situation in the crease for the Minnesota Wild is slightly more ambiguous. Goaltender Filip Gustavsson opted for offseason hip surgery to address chronic wear and tear accumulated over the past several seasons.
Wild General Manager Bill Guerin noted that the procedure was not the result of a single acute injury sustained during the playoffs, but rather a necessary maintenance surgery to prolong Gustavsson's career and restore his lateral mobility.
Gustavsson's readiness for the start of training camp remains in question. Hip surgeries for goaltenders require meticulous rehabilitation to ensure the joint can handle the extreme butterfly movements and explosive pushes required by the position.

Gustavsson's readiness for the start of training camp remains in question.
If Gustavsson is delayed, the Wild are well-positioned to pivot. Rookie goaltender Jesper Wallstedt, who impressed during his late-season call-ups and playoff appearances, is prepared to shoulder a heavier workload if necessary.
In Columbus, the Blue Jackets are welcoming back a familiar face after a grueling year of rehabilitation. Forward Justin Danforth suffered a broken kneecap in mid-October, an injury that derailed his entire 2025-26 campaign.[1]
The complex fracture required two separate surgeries to properly stabilize the joint. Danforth spent the winter immobilized, watching from the sidelines as his teammates navigated a challenging regular season.[1]
Fortunately, the extensive medical intervention was successful. Former General Manager Jarmo Kekalainen recently confirmed that Danforth is "pretty close to being healthy" and will face no restrictions heading into the 2026-27 season.[1]
A similarly frightening medical situation has been resolved in Buffalo. Sabres forward prospect Jiri Kulich was sidelined in November after doctors discovered a blood clot, a condition that immediately halted his season and required specialized care.[1]
Kulich underwent a medical procedure earlier this spring to completely remove the clot. He was granted access to top specialists at the Mayo Clinic, ensuring he received the highest standard of vascular care.[1]

The 22-year-old has already resumed non-contact skating and is steadily rebuilding his cardiovascular conditioning. Kulich recently told reporters he expects to be a "full-go" for training camp, eager to compete for a permanent roster spot in Buffalo.[1]
Meanwhile, the Edmonton Oilers are monitoring the recovery of veteran forward Mattias Janmark. Janmark had been battling a nagging upper-body issue since the Olympic break, ultimately opting for shoulder surgery in early March.
By choosing to undergo the procedure before the season concluded, Janmark sacrificed his playoff eligibility to ensure his long-term health. Head coach Kris Knoblauch confirmed the surgery was successful and aligned with a six-month recovery window.
Janmark is currently progressing through his physical therapy milestones and is fully expected to join the Oilers on the ice when training camp begins in September.
Across the league, the narrative of the offseason is one of resilience. From complex joint reconstructions to vascular procedures, NHL medical staffs are successfully navigating severe ailments, ensuring that the league's top talent will be ready when the puck drops on a new season.[2]

Viewpoints in depth
Sports Medicine Professionals
Focusing on the advancements in surgical techniques and rehabilitation.
Medical staffs across the NHL emphasize that modern surgical interventions—such as advanced mesh repairs for sports hernias and minimally invasive arthroscopic hip procedures—have drastically reduced recovery times. Doctors prioritize not just returning the athlete to the ice, but ensuring the structural integrity of the repaired tissue can withstand the unique biomechanical stresses of professional hockey.
NHL Front Offices
Managing roster construction and salary cap implications during summer recoveries.
For general managers, offseason surgeries introduce a layer of strategic complexity. Front offices must balance the optimism of a player's recovery timeline against the harsh realities of the salary cap. If a player like Filip Gustavsson is delayed, management must decide whether to sign a veteran backup or trust an unproven rookie, all while navigating the intricate rules of Long-Term Injured Reserve.
The Players' Perspective
The mental and physical grind of isolated summer rehabilitation.
From the athletes' point of view, the offseason ceases to be a period of rest and instead becomes a grueling, isolated job. Players recovering from major surgeries often spend four to five days a week in physical therapy while their peers vacation. The mental resilience required to endure this solitary grind is immense, with players heavily relying on team psychologists and peer support networks to stay motivated.
What we don't know
- Whether Filip Gustavsson will be fully cleared for the opening week of the regular season.
- If any of the recovering players will face minor setbacks or require load management during training camp.
Key terms
- Sports Hernia
- A strain or tear of any soft tissue (muscle, tendon, ligament) in the lower abdomen or groin area, common in sports requiring sudden changes of direction.
- Long-Term Injured Reserve (LTIR)
- An NHL salary cap mechanism that allows teams to exceed the cap limit to replace a player who is expected to miss at least 10 NHL games and 24 days.
- Non-Contact Skating
- A phase in a hockey player's rehabilitation where they are allowed to skate and practice puck handling but are forbidden from engaging in physical contact or drills that risk collision.
