Tennis: Dokic suffers thigh injury

Former world number four Jelena Dokic will need to rely on an organiser's invitation for next month's Australian Open tennis championship after pulling out of the wildcard qualifying tournament with a thigh injury.

Dokic had been trailing 16-year-old Olivia Rogowska 6-3, 3-1 in the quarter-final of the tournament when she called for the trainer and then withdrew from the match.

A former Wimbledon semifinalist, Dokic, 24, has hardly played since she won the Australian Open wildcard qualifying tournament in late 2005 but was then knocked out in the grand slam's first round by France's Virginie Razzano.
