It has been claimed that while Sinner may only need a few days to recover, a worst-case scenario could see him miss the tournament altogether.

Steven Buchwald, health expert at Manhattan Mental Health, told Express Sport: "Athlete withdrawals often signal a combination of physical and psychological stress.

"In Sinner’s case, subtle body language cues like slowed footwork, shallow breathing, head tilts, and brief pauses between points may have indicated his body was under strain.

"Psychological stress can amplify fatigue, affecting coordination and decision-making. Recovery timelines for acute illness vary. Mild viral infections may resolve in three to five days, while more serious illnesses may take one to two weeks or longer."

Buchwald went on to list several ways in which Sinner could maximise his recovery, including rest, hydration and gradual training as well as using stress-reduction techniques such as visualisation and practicing mindfulness.

He added: "With these steps, athletes can optimise recovery and improve the likelihood of performing at their best at the next event.

"Sinner’s decision to withdraw, while disappointing for fans, likely maximises both his physical health and competitive prospects."

Sinner recently said that he would be 'ready to push' for the title at the US Open, as long as he manages to shake off his illness in time.

"I love Grand Slams a lot, these are the main tournaments for my season and for my career," he said. "The US Open is going to be a tough tournament but at the same time I'm looking forward to it.

"If I'm ready, physically and mentally, I will be ready to push. So as I said, now a couple of days of recovery and then we will get again back to work. Hopefully we will be ready so for sure, the main goal here in the US."
