Stefanos Tsitsipas revealed he considered retirement in 2025 due to a severe back injury that left him unable to walk for two days. The injury, which intensified after a US Open loss, caused him to question his ability to continue playing at an elite level. After months of pain and doubt, Tsitsipas underwent intensive treatment and rehabilitation, completing five weeks of pain-free training. His focus for 2026 is on staying healthy and rebuilding trust in his body.
