Marwan ElShorbagy will compete in the second round of the El Gouna International after first round opponent Ramy Ashour's campaign was brought to a premature end through injury.
Three-time winner and 2015 champion Ashour had returned to competitive action during last month's British Open following an extended injury absence but appeared to suffer a reoccurrence of the hamstring difficulty that has plagued his career over the past three years as he struggled to move on court to the man who last week won the Grasshopper Cup.
As a result Ashour was forced into shaking his opponents hand at the end of the second game.
The defeat also rules out any hope of qualifying for the end-of-season Dubai World Series Finals next month.
“Ramy is a great players – he's won this tournament three times,” said ElShorbagy. “I didn't expect what happened today – it's sad what has happened to him.
“When he's around it is great for the sport and the players, I just hope he can fix all his injuries because when he's playing fit the sport is in a better place.
“Before playing today I just wanted to enjoy the experience and make the most of it. Sadly that didn't happen today but last week in Zurich gave me a lot of confidence. I can't wait to be back on the court again tomorrow.
“To play in Egypt is a great opportunity and for me I've never made the quarters here before so I'll give it a big push tomorrow.”
