British No 1 Laura Robson's return to action at the Hobart International was cut short when she retired from her first-round match against Yanina Wickmayer due to injury.
Robson was playing her first match of the season after a wrist problem forced her out of the ASB Classic in Auckland.
The 19-year-old won the first set 6-4 but, after serving a double fault to gift her Belgian opponent an early break in the second, she pulled out of the match.
It is a further setback for Robson ahead of the Australian Open, which gets under way in her birth city of Melbourne on January 13.
A post on the tournament's official Twitter feed indicated that Robson's injury was a recurrence of her previous problem.
It read: "The official reason for Robson's mid-match retirement today was her wrist."
