Sharapova seeks a swift return as she pulls out of Miami with injury
Maria Sharapova has withdrawn from next week's Miami Open after suffering an injury to her left forearm, organisers announced on Friday.
The five-time Grand Slam champion has been replaced in the main draw for the Florida showpiece by American Jennifer Brady, a statement said.
"I am really sorry that I have to withdraw from one of my favourite tournaments with my left forearm injury," said Sharapova.
"I am doing everything possible to return to the tour as soon as possible."
Sharapova's withdrawal comes after a disappointing early exit at Indian Wells in California this week, where she lost her opening match against rising Japanese star Naomi Osaka.
That defeat prompted a split with coach Sven Groeneveld, who was axed on Thursday after four years of working with the Russian star.
World number one Roger Federer equalled his best start to a season when he beat South Korea's Chung Hyeon to reach the Indian Wells Masters semi-final.
The defending champion claimed his 16th victory of 2018 with a 7-5 6-1 win over the world number 26 in California.
