Despite an incident that threatened Roland Garros on Tuesday Jo Wilfried Tsonga and Stan Wawrinka emerged as the tournament’s semi-finalist.
A large rectangular metal panel fell from underneath the TV commentary boxes, hitting spectators on the top row.
The incident left a silver-haired spectator and two others injured as the stricken fans were led away by first-aiders.
Tsonga was getting the crowd into a frenzy as he charged into a 6-1 5-2 lead against Japan’s Kei Nishikori before the screams of those affected were heard.
The two players were ushered off court for 40-minute and 12 rows of spectators were evacuated and the area cordoned off.
But Tsonga’s returned to finish off Nishikori in the second set wining 6-1 6-4 4-6 3-6 6-3.
Wawrinka beat his rival Roger Federer 6-4 6-3 7-6 for the first time on a grand slam stage.
