What Is an ACL Tear? Jimmy Butler's Season-Ending Knee Horror Explained
Warriors star Jimmy Butler sidelined with torn ACL, putting Golden State's championship hopes in jeopardy

Jimmy Butler's night at Chase Center started like any other, with the Golden State Warriors cruising to a 135-112 win over the Miami Heat. But the celebration quickly turned into shock when the 36-year-old All-Star crumpled to the floor with an injury that will sideline him for the remainder of the season.
The basketball world is left asking: what exactly is an ACL tear, and how will this affect both Butler and the Warriors?
How the Injury Happened
With under eight minutes remaining in the third quarter, Butler received a pass from Brandin Podziemski and landed awkwardly. He immediately grabbed his right knee and let out a scream, unable to put weight on the leg. Teammates quickly helped him to the locker room, and the Warriors later confirmed he would not return to the game.
Initial reports were vague, simply noting a 'knee injury.' But by Tuesday morning, ESPN's Shams Charania reported the worst-case scenario: a torn anterior cruciate ligament, or ACL, in Butler's right knee, ending his season.
Warriors coach Steve Kerr described the locker room mood as subdued, with the team waiting anxiously for confirmation. 'We're all concerned,' Kerr said. 'Subdued. Waiting to hear the news.'
What Is an ACL Tear?
The anterior cruciate ligament is a vital band of tissue connecting the thigh bone (femur) to the shin bone (tibia). It stabilises the knee, preventing the shin from sliding forward or twisting too far. ACL tears can range from mild sprains to complete ruptures.
These injuries often occur during sports involving sudden stops, pivots, or awkward landings – exactly the kind of movement Butler experienced. Symptoms include severe pain, swelling, instability, and sometimes a popping sound at the time of injury. Recovery can involve surgery, months of rehabilitation, and careful management to return to full competitive play.
For an elite athlete like Butler, a torn ACL not only ends a season but also requires a long road to regain peak form.
Butler's History With Knee Injuries
This is not the first time Butler has faced significant knee issues. In 2018, he tore his meniscus while playing for the Minnesota Timberwolves, an injury that cost him several weeks but did not require season-ending surgery. More recently, he sprained his MCL in 2024 while with the Miami Heat, which sidelined him for several games.
Despite these past setbacks, Butler has been a force for the Warriors. Through 37 games this season, he averaged 20.1 points, 5.6 rebounds, 4.9 assists, and 1.4 steals while shooting 51.9% from the field. He ranks second on the team in scoring behind Stephen Curry and has provided critical two-way impact.
What This Means for the Warriors
Butler's injury comes at a critical time for Golden State, who had won 12 of their past 16 games and were climbing the standings. Losing a player of Butler's calibre creates both an immediate gap on the court and potential long-term ramifications for the team's championship aspirations.
Stephen Curry commented on Butler's characteristic resilience: 'He was still cracking jokes over there while he was on the ground. In true Jimmy fashion, he's always gonna have a good time no matter what the situation is.'
The Warriors now face the challenge of reshaping rotations and relying on remaining veterans to fill the void. While Golden State has shown flashes of brilliance this season, the absence of a key leader like Butler underscores the fragile nature of team dynamics and playoff ambitions.
ACL tears are among the most feared injuries in professional sports, and Jimmy Butler's collapse on Monday night is a stark reminder of the fine line athletes walk between peak performance and disaster. For the Warriors, the road ahead just became significantly steeper, and fans will be watching closely to see how the team adapts without one of its most dynamic stars.
