British number one Emma Raducanu has pulled out of the Transylvania Open in Romania with a wrist injury.
Raducanu has struggled with injuries during her first full year on the WTA tour as she has tried to build on her 2021 US Open victory.
Most recently, she retired injured from her Korea Open semi-final against Latvian Jelena Ostapenko.
Raducanu, who is 67th in the women's rankings, then played at the Ostrava Open but lost to world number 11 Daria Kasatkina, of Russia, in the first round.
Earlier this year, Raducanu was knocked out in the second round of Wimbledon by France's Caroline Garcia.
