Venus Williams withdrew from the Australian Open owing to an injury, raising questions about Iga Swiatek's ability to compete.

The American lost his opportunity to compete in the opening grand slam of the year due to injury this week at the ASB Classic.

After losing to Chinese player Zhu Lin in the tournament's second round on Thursday in Auckland, it was announced on Saturday that Williams will not be competing at Melbourne Park.

Seven-time grand slam singles champion and 14-time major doubles champion, the 42-year-old has displayed tremendous endurance during her storied career.

Williams lost her two singles finals in 2003 and 2017 and won four of her grand slam doubles titles in the Australian Open.

Williams' wildcard spot has been given to Australian Kim Birrell nine days before the tournament begins.

The Adelaide International 2 will take place next week despite the withdrawal of world number one Swiatek owing to a shoulder issue.

When Swiatek lost against Jessica Pegula in Friday's United Cup match between Poland and the United States, she broke down in tears.
