Stefanos Tsitsipas has withdrawn from the Rolex Shanghai Masters, citing a leg injury.

The Greek, who has also battled back pain this season, had been due to play Czech qualifier Dalibor Svrcina Saturday, last match on Grandstand 2. Australian Aleksandar Vukic comes into the draw as a lucky loser.

Tsitsipas’ resolve has been tested this year. After five Top 10 finishes between 2019-2023, and a No. 11 finish last year, the former World No. 3 has slipped to No. 25 in the PIF ATP Rankings.

The 2019 Nitto ATP Finals champion has a 22-18 record on the year, according to the Infosys ATP Win/Loss index.
