A right wrist injury has forced India's Sania Mirza to withdraw from the $2.1 million Sony Ericsson Open tennis tournament in Miami.

Sania, seeded 29th in the Masters event, had been battling the injury since her pre-quarterfinal appearance in the Pacific Life Open last week.

The 21-year-old was handed a bye in the first round along with other seeds and was to take on wildcard Sabine Lisicki of Germany in the second round.

But injury forced her to pull out of the event Wednesday, giving loser Mariya Koryttseva of Ukraine a place in the main draw.
