Emma Raducanu has suffered another injury setback after withdrawing from the Miami Open ahead of her first-round match.
The 21-year-old, who was given a wild card, was set to play China’s Wang Xiyu on Tuesday but has been forced to pull out of the tournament due to a low back injury, the WTA has announced.
It is another blow for Raducanu in her attempts to establish herself as a consistent presence on the WTA Tour.
The former US Open champion spent the second half of last year recovering from ankle and wrist surgery that saw her sidelined from May, the latest in a long line of injury problems since winning at Flushing Meadows in 2021.
She made her return at the start of this year and showed promising signs by making the third round of the BNP Paribas Open at Indian Wells before losing to Aryna Sabalenka.
Raducanu’s withdrawal in Miami casts doubt over her availability for Great Britain’s Billie Jean King Cup tie with France on April 12-13.
