Holger Rune to begin Achilles comeback at Hamburg

Denmark's Holger Rune plans to return from his ruptured Achilles tendon at next month's Hamburg Open in Germany.

The former World No. 4 sustained the injury in the semifinals of Stockholm's Nordic Open on Oct. 18.

Rune, 22, announced his entry into the May 16-23 clay-court tournament in Hamburg on Instagram Thursday.

"The comeback begins," the caption read, in all caps.

Rune has dropped to No. 29 due to his layoff. The mid-May return would mean an absence of only seven months, shorter than the typical nine-to-12 month timeline for a torn Achilles.

"I have been locked in on my rehab work since the start of my injury and spent hours on heavy rehab surrounded by specialists from Denmark and Aspetar (a private hospital in Doha, Qatar) and my team and I just can't wait to be back on court now," Rune said in a statement to The Athletic.

Rune has won five titles on the ATP Tour, most recently defeating Spain's Carlos Alcaraz to win the Barcelona Open in April 2025. Rune has yet to reach the semifinals in any of the Grand Slam events.
