Ana Ivanovic joined the long list of injury withdrawals from the Porsche Grand Prix tournament.
The Serb hurt her shoulder in practice Sunday and pulled out of the US$650,000 event starting Monday.
Other players who withdrew earlier included Kim Clijsters, Justine Henin-Hardenne, Maria Sharapova, Lindsay Davenport and Serena and Venus Williams.
Amelie Mauresmo is the top-seeded player, followed by Svetlana Kuznetsova, Elena Dementieva and Nadia Petrova. They all have a bye into the second round.
