Australian tennis player Thanasi Kokkinakis said he has undergone surgery in a bid to resolve a lingering pectoral injury.
The 28-year-old aggravated the problem in his five-set loss to Jack Draper in the second round of the Australian Open on Jan. 15. He retired injured midway through a doubles match with Nick Kyrgios the following day.
"Been struggling for a little while with this ... Probably my toughest challenge to date," Kokkinakis wrote on X with a picture of himself in a hospital bed with his right arm in a sling. "Trying to find answers to a ongoing Pec injury that I haven't been able to fix. Let's see how this goes. Thank you for all your ongoing support."
Kokkinakis, who reached a career-high singles ranking of 65th in 2023, is currently 84th and has one title to his name.
He has enjoyed much more success in doubles, capturing a Grand Slam trophy with Kyrgios at the 2022 Australian Open.
