The athlete entered the previous US Open as the 26th seed.
Stefanos Tsitsipas has revealed he thought about ending his career due to severe spinal pain throughout the season.
At 27 years old, the player once ranked as high as third globally, finished as runner-up against Novak Djokovic at both the 2021 French Open alongside the 2023 Australian Open.
Currently placed as the world's 36th best player after a limited schedule post a second-round departure in New York in August, he stated that ongoing treatment is finally showing positive results.
"I'm most excited lies in seeing how my training holds up under actual training with regard to my back," said Tsitsipas.
"The biggest fear was whether I could complete a match," the athlete continued, noting the injury had troubled him "over the last half a year or more."
"I would wonder, 'Am I able to play another contest without discomfort?'"
"It was genuinely scary after the defeat in Flushing Meadows [to Germany's Daniel Altmaier]. I could not to walk for two days. That is the moment begin to question the path ahead."
Tsitsipas further mentioned being content with his current recovery plan following the completion of an extended period of pre-season training without any pain.
His next appearance for Greece at the team event, where they face Team Japan led by Osaka and the British team captained by Raducanu. The tournament will be held in Perth and Sydney from 2 to 11 January, just before the Australian Open.
"The greatest victory for 2026 would be to stop worrying over completing bouts," he stated.
"It provides fantastic feedback to know you completed a pre-season in good health – I wish for it to last. I want to deliver in 2026 and at the United Cup.
"I have done the work. The most important thing is complete faith that I can return to my previous level. I will try all means to make it happen."
