Bianca Andreescu, of Canada, serves against Ekaterina Alexandrova, of Russia, in the first set of a match at the Miami Open tennis tournament, Monday, March 27, 2023, in Miami Gardens, Fla. AP
While attempting a return, Andreescu injured the ankle, collapsing to the court as she yelled in pain.
After receiving medical attention on court she was lifted into a wheelchair and taken off court in tears.
While receiving treatment Andreescu yelled "I've never felt this much pain."
Andreescu was hugged by her Russian opponent before she was taken off court, the WTA later confirming a left ankle injury.
In 2021 she retired from the final in Miami after suffering a right ankle injury against Ashleigh Barty
The 22-year-old, who won the US Open in 2019 but then missed all of 2020 due to injury, returned to the circuit last April after a six-month break.
In Miami she has looked very much back to her best with wins over Emma Raducanu, Maria Sakkari and Sofia Kenin.
The fourth round match had been subject to a lengthy rain delay but the court did not appear to wet or to be a factor in the injury.
