A Tier-II tournament ranks below the Masters Series and the Grand Slams, according to the WTA.

Sania's mother Nasima Mirza confirmed that Sania had been offered a wildcard but is unable to take part.

The injury has troubling Sania for a month. She braved the injury to win the WTA Hyderabad Open last week, and had reached the third round of the 2005 Australian Open in January.

She had pulled out of the WTA event in Columbia, which was to start on February 14.
