BRITAIN'S Emma Raducanu has withdrawn from the Miami Open with a lower back injury, tournament organisers said on Tuesday, the latest setback for the 21-year-old.
Raducanu spent eight months out with wrist and ankle problems last year but returned to action in January and had an encouraging performance at Indian Wells last week where she reached the third round.
“I have been experiencing lower back pain and at this stage of my return to competition I don’t want to risk anything happening,“ said Raducanu.
“I really tried my best to be ready and I’m sad to be pulling out of Miami as it’s a cool tournament but wish the event all the best.”

She was beaten in the Indian Wells third round by world number two Aryna Sabalenka.
Wang will now face Slovakian qualifier Anna Karolina Schmiedlova.
