Nick Kyrgios’ Australian Open rehearsal has hit a hurdle he withdrew from the Melbourne Summer Set due to asthma.
Kyrgios was set to play against Alex Molcan on Rod Laver Arena on Tuesday night but retired six hours before he was due on court to play.
The exit leaves Kyrgios with just one lead-up tournament - the Sydney Tennis Classic - before he begins his Australian Open campaign. The 26-year-old has not played since the Laver Cup in late September.
He has spent the last three months recuperating from a knee injury and spending time with family and friends in Canberra.
