The 23-year-old Yorkshireman, ranked 14th in the world, has withdrawn from next week’s Sydney International.
The event had been set to be Edmund’s final tournament before the very first Grand Slam of the year, which starts in Melbourne on 14 January.
Edmund reached his original Slam semifinal at this past season’s tournament.
“I’m disappointed that I will not be able to go back to Sydney,” he explained.
“that I need to focus on my preparations for the Australian Open and do everything I could to be fit for its very first Grand Slam of the year”
