The main discomfort for Stefanos is located in the serve," says Tsitsipas's physiotherapist

Stefanos Tsitsipas has not played in an official competition since the US Open. In an interview with Tennis24, the Greek player's physiotherapist spoke about his injury.

He states: "His back problem is in the rehabilitation phase. He is following a rehabilitation protocol prescribed by the doctor who recently treated him. It is a complex injury. Specifically, the main discomfort Stefanos currently feels is located in the serve.

When an athlete of Stefanos's caliber suffers so much on the serve, which is one of his main weapons, he approaches the match with a handicap.
