A wounded Nick Kyrgios has declared he cannot see himself making another singles appearance at the Australian Open after crashing out in his long-awaited grand-slam comeback.
The 29-year-old Australian said a lingering abdominal strain plagued his serve in a 7-6 (7-3) 6-3 7-6 (7-2) first-round loss to young Scot Jacob Fearnley on Monday night.
