Serena Williams withdraws from two events due to back injury
Top-ranked Serena Williams withdrew Friday from the Qatar Open and the Indian Wells event because of a back injury sustained last month in the Australian Open.
The Qatar Open begins Monday in Doha, and the BNP Paribas Open is March 3-16 in Indian Wells, Calif.
In a statement released by the Indian Wells event, Williams said: ''After careful consideration, I will not return to the Indian Wells BNP Paribas Open this year. I send my best wishes to everyone involved with the tournament.''
