Maria Sharapova, five times a grand slam champion, returned to competition the past week at the Mallorca Open in Spanish island.
Sharapova, 32, underwent a second surgery on her right shoulder in February.
She will not play at Eastbourne Wimbledon starting this week on Monday in Britain.
Tennis is no longer as natural for Sharapova and she has not been the same player since her first surgery a decade ago.
She is currently ranked 85th.
Fifteen years ago, Sharapova arrived at Wimbledon and produced one of the biggest tennis stories in history.
