Reigning French Open champion Maria Sharapova was forced to withdraw from the season-opening Brisbane International yesterday with a right collarbone injury.u00a0Sharapova sent scans of her injury to her doctor in New York, who advised her not to do any overhead training for at least a week.

“So to be fair I haven’t really given myself a chance to pretty much hit any serves or anything over my head, I’ve just been practising groundstrokes. So I just kind of ran out of time here,” said the Russian World No 2. It is the second year in a row that Sharapova has withdrawn from the tournament without playing a shot.
