Injury Timeline

Klay Thompson suffered a torn ACL in his left knee during Game 6 of the 2019 NBA Finals. He subsequently missed the entire 2019‑2020 season. While rehabbing from that injury, he sustained a torn Achilles tendon in his right leg during a pickup game in November 2020, causing him to miss the 2020‑2021 season as well. These two major setbacks sidelined one of the NBA’s elite shooters for over two years. The ACL tear required immediate surgery and a long rehabilitation phase. Just as he was nearing a return, the Achilles injury set him back another full year, making his comeback one of the most anticipated in recent NBA history.

Rehabilitation Process

Thompson committed himself to a rigorous rehabilitation regimen under the supervision of the Warriors’ medical staff. He focused on strength training, mobility, and gradually progressing from non‑weight bearing activities to full basketball movements. His rehab included low‑impact exercises, aquatic therapy, and controlled court work. For the ACL, the early phase involved restoring range of motion and reducing swelling. For the Achilles, the emphasis shifted to protecting the healing tendon while slowly rebuilding calf strength. Both injuries required meticulous, stage‑by‑stage progression to avoid re‑injury. Thompson’s patience and consistency were vital throughout this demanding process.

Mental Resilience

Recovering from two major injuries required immense mental strength. Thompson concentrated on short‑term goals, leaned on teammates and family for support, and emphasized patience throughout the process. He famously said that he visualized his return and never doubted he would play again. His ability to stay positive, trust the rehabilitation program, and remain engaged with the team became key factors in his successful comeback. He frequently traveled with the Warriors, attended practices, and mentored younger players, which helped maintain his connection to the game and boosted his morale.

Return to Play

After missing 941 days of game action, Thompson made his highly anticipated return on January 9, 2022, against the Cleveland Cavaliers. He scored 17 points in his debut, showcasing his trademark shooting ability. He continued to regain his rhythm over the season, playing in 32 regular season games and helping the Warriors win the 2022 NBA championship — a remarkable achievement given the injuries he overcame. In the playoffs Thompson averaged over 20 points per game and provided elite floor spacing. His defense and timely shooting were crucial for Golden State in their six‑game victory over the Boston Celtics.

Training and Conditioning

To manage the toll of two major leg injuries, Thompson adapted his training routine. He incorporated more load management days and focused on core stability, flexibility, and body maintenance. His shooting form remained largely unchanged, but his defensive movement and lateral quickness required gradual rebuilding. Klay worked closely with the Warriors’ strength and conditioning coaches to design a program that addressed the specific weaknesses caused by his injuries. He emphasized glute and hamstring work to offload the knees and calves, and adopted a more thorough warm‑up and cool‑down routine. His dedication to conditioning allowed him to perform at an elite level.
