Denmark's Rune set for Achilles surgery

Holger Rune will undergo surgery next week to repair a torn Achilles suffered during Saturday's Stockholm Open semi-final, he said on Sunday.

The Danish world number 11 was leading 6-4 2-2 against Ugo Humbert when he had to retire from the match, adding to a long list of players who have suffered injuries this season.

"It’s gonna be a while before I can step on court again. It’s tough. I had so much joy on court in Stockholm and it’s unbearable to think that I will not feel this energy for some time now," the 22-year-old posted on Instagram.

"My Achilles is full broken on the proximal part meaning I need operation already next week and from here rehabilitation."
