Egypt's Ramy Ashour was eliminated from the World Championship semi-final after suffering an injury in his game against Englishman Nick Matthew on Saturday.
The 26-year-old won the first game 11-6, lost the second 11-2 before withdrawing in the third after feeling pain in his hamstring.
"It's obviously a big disappointment for me. I’m going to go and see what they say in Aspetar, the clinic in Qatar, to see once again what’s wrong with my legs," Ashour was quoted as saying by Squash Site.
"They say I suffer from fatigue in the hamstring, and they are not sure if there is something I can do to prevent this from happening again and again."
Ashour reached the semi-final after easing past India’s Saurav Ghosal with a 3-0 victory on Thursday, extending his winning streak to 52 matches.
"Now, I can’t complain, I had a good season, a great season, and I have to take that loss like a man, and accept that other people had bad times as well," he added.
"But I have no fitness coach, and I’ve been stuffing myself with anti-inflammatory pills for months now, hoping that my body would hold. But the body just can’t take it anymore.
Fellow Egyptian Mohamed Elshorbay faces Frenchman Gregory Gaultier in the other semi-final later on Saturday.
