WBA world lightweight champion Vasyl Lomachenko will have surgery on his shoulder on Wednesday and is expected to be out of the ring until December.
Lomachenko, 30, beat Jorge Linares on 12 May to become the fastest three-weight world champion in history in just his 12th professional fight.
The Ukraine fighter tore the labrum in his right shoulder during the bout.
“I was aware something was not right straight away,” he said. “I’ll be back in the ring this year.”
Lomachenko, who has held world titles at featherweight and super-featherweight, shared a picture of him having his injury assessed on social media.
His promoter Bob Arum attended the session and has reportedly said his fighter could return to the ring on 8 December.
But the specialist set to operate on the two-time Olympic champion believes there is evidence Lomachenko dislocated his shoulder during his Linares win and feels a return in 2018 is realistic.
Tomorrow I undergo surgery for a torn Labrum in my right shoulder suffered during the 2nd round of my fight against Jorge Linares. I was aware something was not right with my shoulder straight away, but I could not disappoint my fans with excuses. Thank you for the overwhelming kind words I’ve already received. I’ll be back in the ring THIS year 🤖
