World number one Serena Williams has pulled out of next week's Sony Ericsson Open due to a knee injury, according to tournament organisers.

Serena Williams of the USA returns to Petra Kvitova of the Czech Republic, in their second round match at the Australian Open tennis tournament in Melbourne 21 January 2010. Williams defeated Kvitova 6-2 6-1 - 0

The American's withdrawal is another blow to the tournament after former Wimbledon champion Maria Sharapova and world number two Dinara Safina had already pulled out.

Williams has won the Key Biscayne event five times.

Venus Williams and Svetlana Kuznetsova headline the women's field while the men's top three - Roger Federer, Novak Djokovic and Rafael Nadal are joined by American Andy Roddick and defending champion Andy Murray.

The men's competition will be without fifth-ranked Juan Martin del Potro of Argentina due to a wrist injury.
