Jan 14 (Reuters) - Thanasi Kokkinakis' ‌emotional return to tennis ended in heartbreak on Wednesday ‌when the Australian was forced to withdraw from his ‌beloved Adelaide International, admitting his shoulder simply was not ready after nearly a year on the sidelines.

The 29-year-old had battled through a gruelling three-set victory over ‍American Sebastian Korda in the previous round, ‍but the cost proved too ‌high for a body still recovering from pectoral surgery in February.
