MELBOURNE, Australia — Novak Djokovic has moved to clarify how mistakes were made on the immigration document he submitted on his arrival in Melbourne last week, before his visa was revoked and then reinstated in a COVID-19 vaccination saga that has overshadowed the days leading up to the Australian Open.

A statement was posted on Djokovic’s social media accounts Wednesday while he was in Rod Laver Arena holding a practice session.

The nine-time and defending Australian Open champion is in limbo before the Open.

Djokovic won a legal battle on Monday allowing him to stay in the country, but still faces the prospect of deportation because he’s not vaccinated.
