Two-time Australian Open champion Victoria Azarenka withdraws from Wimbledon
Her withdrawal means five-time champion Venus Williams will move up into the top eight seeds.
Former world number one Victoria Azarenka has withdrawn from Wimbledon with a knee injury, organisers said on Thursday.
Belarussian Azarenka , who would have been seeded six at the championships, has not played since retiring from a first-round match at the French Open last month.
It is yet another blow for the two-times Australian Open champion who has been plagued by foot injuries. Her withdrawal means five-times champion Venus Williams will move up into the top eight seeds.
