Australian Open champion Novak Djokovic has pulled out of the ABN Amro Tournament, citing a shoulder injury.
Tournament director Richard Krajicek says Djokovic called him to say the injury will prevent the Serb from training for a week.
The defending champion Robin Soderling will replace Djokovic as the top-seeded player for the tournament in Rotterdam. It starts Monday at the Ahoy stadium.
Djokovic defeated Andy Murray in the Australian Open final on Sunday. Murray is expected to play.
