Clara ThompsonNHL Playoffs Begin April 18, 2026: The Hockey Injuries Every Canadian Fan and Weekend Warrior Should Understand
The Dallas Stars handed the Toronto Maple Leafs a 5-1 defeat in their final regular season meeting on April 13, 2026 — and with the Stanley Cup playoffs officially starting April 18, Canadian hockey fans are about to watch the most physically demanding stretch of the sport's calendar. But behind the spectacular saves and slap shots, the NHL playoffs generate a surge of injuries that physicians and sports medicine specialists track closely. For the millions of Canadians who also lace up skates themselves — from beer-league veterans to young players — playoff season is also a reminder of the physical risks that come with the game.
Here is what sports medicine experts want every hockey player and fan in Canada to understand about the most common injuries in ice hockey, and when a professional assessment becomes essential.
Why the Playoffs Are an Injury Minefield
NHL playoff hockey is played at a faster pace, with higher-impact collisions and more fatigue than regular season games. According to research published in PMC (PubMed Central), concussion rates in the NHL are significantly elevated and have been a persistent focus of the league's safety protocols. Players absorb blows to the head from elbows, shoulder checks, and board impacts — all common elements of playoff-style hockey.
At the amateur level, the same dynamics apply. Every spring, recreational rinks across Canada see an uptick in injuries as weekend warriors ramp up their games for end-of-season tournaments and shinny sessions.
The Most Common Hockey Injuries
1. Concussion Concussion is the single most reported injury in ice hockey at all levels. It results from direct blows to the head or from body impacts that cause rapid head movement. Symptoms include headache, confusion, light sensitivity, nausea, and cognitive fog. According to the Hospital for Special Surgery (HSS), the challenge with concussions in hockey is that symptoms may be delayed — a player who "feels fine" after a collision may experience significant symptoms 24-48 hours later.
Any suspected concussion requires immediate removal from play and evaluation by a physician. Return-to-play protocols exist for a reason: a second concussion before the first has healed — a "second-impact syndrome" — can have severe neurological consequences.
2. MCL (Medial Collateral Ligament) Sprain The MCL, located on the inner side of the knee, is the second most commonly injured structure in hockey. It typically tears when an external force — another player, the boards, or an awkward edge catch — pushes the knee inward. Pain is felt along the inner knee, often accompanied by swelling and instability.
Mild MCL sprains respond well to rest, ice, compression, and physiotherapy. Severe tears, however, may require surgical intervention. A sports medicine physician can use clinical testing and, if necessary, an MRI to grade the severity and design a recovery plan.
3. Shoulder Separation and AC Joint Injuries Falls onto the ice or collisions with the boards frequently cause shoulder separations — specifically injuries to the acromioclavicular (AC) joint. Players experience immediate pain at the top of the shoulder, often with a visible step deformity in severe cases.
Grade I and II AC injuries typically heal conservatively with rest and physiotherapy. Grade III and above may require surgical stabilization, particularly for players who want to return to full competitive activity.
4. Groin and Hip Flexor Strains The skating stride puts enormous repetitive strain on the groin musculature. Adductor (groin) strains are among the most common soft-tissue injuries in hockey, especially in the hips and inner thighs. These injuries often develop gradually, with players "playing through" mild tightness until a full strain occurs.
Physiotherapy, targeted strengthening, and load management are key. Returning too early after a groin strain significantly increases the risk of re-injury and a longer eventual recovery.
5. Skate Lacerations Skate blade lacerations, particularly to the ankle and lower leg, are a known risk in hockey. The American Orthopaedic Society for Sports Medicine (AOSSM) has highlighted the importance of cut-resistant protective gear. Deep lacerations can sever tendons, nerves, or blood vessels — these injuries require emergency evaluation, not ice-and-rest.
When to See a Doctor: The Warning Signs
Many hockey players — at every level — have a tendency to minimize injuries. The culture of "toughness" in hockey is real, but it comes at a cost. Here are the clear signals that warrant a visit to a physician rather than simply sitting out a shift:
- Any suspected head impact accompanied by headache, confusion, dizziness, or nausea — do not wait to see if symptoms resolve
- Knee swelling that develops within hours of an injury — rapid swelling often indicates ligament damage or a meniscal tear
- Inability to bear weight after a lower-body collision
- Numbness or tingling in the hands or feet after a shoulder or neck impact
- Visible deformity at any joint, particularly the shoulder or fingers
- Laceration that will not stop bleeding or involves deep tissue
For minor sprains and muscle strains — discomfort with full range of motion and no swelling — a few days of rest followed by guided stretching may be sufficient. When in doubt, see a professional.
The Weekend Warrior Gap
One of the most important points sports medicine doctors in Canada consistently make is this: amateur players are at higher risk of serious injury than professionals, not lower. NHL players have access to team physicians, athletic therapists, and daily monitoring. A 45-year-old playing Wednesday night beer league does not.
Recreational players are also often less conditioned for the demands of hockey than they believe themselves to be, especially at the start of playoff rounds after winter deconditioning. Fatigue dramatically increases injury risk — tired players take shortcuts on technique that expose joints and muscles to abnormal loads.
