The 19-year-old Czech sensation Jakub Mensik has officially withdrawn from the 2026 Australian Open due to a progressing abdominal muscle injury, granting Novak Djokovic a walkover victory into the quarterfinals.
The announcement came late on Sunday, January 25, just hours after Mensik and his team made the difficult call following exhaustive attempts to manage the issue and keep competing.

Mensik posted an emotional message on social media, explaining that the injury had worsened over the course of his recent matches despite everything he and his support staff had tried to push through.
He expressed deep disappointment at missing what would have been a dream fourth-round encounter against Djokovic—his longtime idol—but emphasized pride in his breakthrough performance at Melbourne Park. Reaching the last 16 of a Grand Slam for the first time represented a massive milestone for the young player, who turned pro only in 2023 and has climbed rapidly into the world’s top 40.
Currently ranked No. 37, Mensik entered the tournament fresh off claiming the Next Gen ATP Finals title late in 2025, and he carried that momentum into the main draw with convincing wins over higher-seeded opponents in earlier rounds. His aggressive serving, powerful baseline game, and fearless attitude had made him one of the most talked-about stories of the first week, positioning him as a serious emerging threat on the ATP Tour.
The withdrawal adds to a concerning trend at this year’s Australian Open, where abdominal injuries have already sidelined multiple players. Mensik becomes the second such case in the past 24 hours, following Naomi Osaka’s earlier exit on night seven due to a similar abdominal strain.
Medical experts and players have noted that the hard courts, combined with the physical demands of long rallies and the hot Melbourne conditions, can contribute to these soft-tissue issues flaring up mid-tournament.
For Djokovic, the No. 7 seed and defending champion in pursuit of an unprecedented 11th Australian Open crown (and 25th major overall), the walkover arrives at a timely moment.
At 38 years old, the Serbian legend benefits from the extra rest and recovery day ahead of the quarterfinals, especially in a loaded bottom half of the draw that still features heavy hitters like Carlos Alcaraz and Jannik Sinner. Djokovic now advances to his 16th Australian Open quarterfinal without having to take the court against Mensik on Rod Laver Arena as originally scheduled for Monday night.
Mensik’s team has indicated he will focus on full rehabilitation in the coming weeks to avoid any long-term setbacks, with the hope of returning strongly for the clay-court swing and beyond. The tennis community has rallied around the young Czech, with many expressing sympathy online and predicting this setback will only fuel his determination for future big-stage moments.
