Danish tennis sensation Holger Rune has confirmed a devastating torn Achilles tendon injury sustained during his Stockholm Open semifinal match on Saturday, October 18, 2025. The alarming diagnosis, confirmed by his mother and manager Aneke Rune, is expected to sideline the 22-year-old for three to six months, necessitating surgery and likely ending his 2025 season prematurely.
The incident unfolded during worrying scenes at the Nordic Open, where Rune, visibly in tears, was forced to retire from his match against Ugo Humbert.
Harrowing Scenes on Court in Stockholm
The injury occurred in the second set of the semifinal clash against Frenchman Ugo Humbert, with Rune leading 6-4, 2-2. During a rally, the World No. 11 suddenly pulled up, clutching his lower left leg and immediately signaling to his box that he could not continue. Eyewitnesses and reports indicate Rune told his physio, through tears, that he “heard a pop” in his Achilles tendon.
The young Dane was seen limping off the court, requiring assistance, a heartbreaking sight for fans and his team. His mother, Aneke Rune, watched on with concern from the stands as her son was helped off.
Official Confirmation of Achilles Rupture
Hours after the incident, Aneke Rune provided a grim update to Danish media outlets, confirming the severity of her son’s injury. “There is no doubt. It is a torn Achilles tendon. It’s three to six months out,” she stated in a text message, adding that Holger was “completely devastated” and would require surgery. Medical staff reportedly confirmed the tear could be seen “with the naked eye.”
Significant Impact on Season and Career Trajectory
This devastating Achilles tear means Rune will miss a substantial portion of the tennis calendar, effectively ruling him out of the remainder of the 2025 season. The recovery period for a surgically-repaired Achilles tendon is extensive and challenging, with athletes often facing lengthy rehabilitation. There is a possibility, even likelihood, that Rune could miss almost all of the 2026 ATP season.
The timing is particularly cruel for Rune, who, at 22 years old, was attempting a late push to qualify for the prestigious ATP Finals in Turin, sitting at World No. 11 in the race. His Stockholm Open campaign was critical for these aspirations.
A History of Physical Challenges
This latest setback adds to a series of physical challenges for the young star. Rune had already been managing a left hamstring issue during his quarterfinal match in Stockholm, admitting he was not at “100 percent” prior to the semifinal. Despite his young age, Rune has previously contended with chronic back pain and other muscle injuries that have hindered his momentum since his breakout victory at the Paris Masters in late 2022.
The tennis community has reacted with widespread sympathy, with fellow players like Jack Draper and Taylor Fritz calling for the ATP Tour to “adapt” its schedule in light of the increasing number of injuries and player burnout. Ugo Humbert, Rune’s opponent, expressed his deep disappointment for Holger, wishing him a “speedy recovery.”
The road to recovery will be arduous for Rune, and the tennis world will be keenly watching his progress as he aims to return to elite competition.
