• Former world No 13 pulls out of charity match due to abdominal strain
• 29-year-old due to play first tennis major since 2022 at Melbourne Park

The injury comeback for tennis player Nick Kyrgios has stalled, after a new ailment scuppered his Australian Open preparations and put the former world No 13 in doubt for his home grand slam.

The 29-year-old has been rehabbing a surgically repaired wrist and returned to the court at the Brisbane International last week, where he showed promise despite a loss in his first round singles match.
