Fourth seed Grigor Dimitrov reached the French Open second round on Sunday, even if he wasn't exactly sure who he was facing on the other side of the net.
Dimitrov had been drawn to face experienced Viktor Troicki in the tournament opener on Philippe Chatrier Court.
However, just before he was due to go on court, Troicki withdrew with a back injury, allowing Egyptian world number 182 Mohamed Safwat to make his Grand Slam debut. In the process, he became the first Egyptian since Tamer El Sawy at the 1996 US Open to feature in a major.
"I was warming up and my coach said, 'hey look' and we saw up on the board that I was playing a different opponent," said 27-year-old Dimitrov, a former Wimbledon semi-finalist.
"I didn't expect that."
