Australian 22-year-old Talia Gibson is through to her first tour-level singles final at the Singapore Open after Russian opponent Tatiana Prozorova withdrew before their semifinal.
Prozorova took aim at WTA concussion protocols, saying a physio "pressured" her into pulling out after she was hit by a crash in an earlier doubles match.
Australian Talia Gibson has progressed to her first singles final on the main WTA tour at the expense of Tatiana Prozorova, who says she was "pressured" into withdrawing from their semifinal after failing part of a concussion test.
Gibson reached the final of the Singapore Open, where she will face a former grand slam finalist, as this year's French Open runner-up Maya Chwalinska and 2021 US Open finalist Leylah Fernandez face off in their final-four clash.
The Russian stayed on the ground for some time before receiving a medical timeout and retiring from the match with partner Sofya Lansere, handing Australian Ellen Perez and Miyu Kato the victory.
The world number 180, who stunned popular Filipino third seed Alex Eala in the second round, said her "dream week came to an end" and she was upset with the process.
On Instagram, Prozorova wrote that Kato's crash had mostly hit her shoulder and only "grazed" her cheek.
If forced to sit out for six days, the 22-year-old will miss the chance to qualify for the China Open in Beijing, which starts on September 30.
