Third seed Jelena Jankovic battled through pain to reach the third round of the French Open today.
The Serbian hurt her forearm midway through the second set against New Zealand's Marina Erakovic, but fought on to seal a 6-2 7-6 (7/5) win and set up a clash with 28th seed Dominika Cibulkova.
After winning the first set quite comfortably in 37 minutes, Jankovic started having problems with her right forearm in the fifth game of the second.
She took the game to go 3-2 up but called on the trainer and complained her forearm was swollen.
The arm was massaged and Jankovic took some painkillers before continuing.
The injury did not initially seem to affect the 23-year-old, who broke the next game to go 4-2 ahead.
But she was pegged back and received further treatment on her forearm in between games.
Erakovic, ranked 80 in the world, broke again to go 6-5 ahead but Jankovic did the same moments later to take the set to a tie-break, which she won.
Slovakia's Cibulkova had earlier defeated Milagros Sequera 6-3 6-0 in 53 minutes on Court Five.
Eighth seed Venus Williams was also an early winner in overcast conditions on the fifth day, beating Tunisia's Selima Sfar 6-2 6-4.
The American took the opening set at the first time of asking in 35 minutes but had more trouble in the second.
She was broken in the fifth game to go 3-2 down and then squandered a clutch of break points of her own before eventually succeeding to draw level at 3-3.
Williams moved 5-4 ahead and then broke again to clinch the match.
She will next play 26th seed Flavia Pennetta, the Italian who beat Anastasia Pavlyuchenkova 3-6 6-1 6-1.
Elsewhere, unseeded Czech Iveta Benesova, a qualifier, beat Shuai Peng 6-4 6-3 to go through to the third round.
And local favourite Amelie Mauresmo was dumped out in the second round in a shock 6-3 6-4 defeat by Spanish qualifier Carla Suarez Navarro.
Two-times grand slam winner Mauresmo, who before Roland Garros had not played since last month's Fed Cup tie in Japan due to an abdominal injury, struggled with her serve and the 22nd seed bowed out after 72 minutes.
Suarez Navarro, who knocked out Pauline Parmentier in the first round, could face a third Frenchwoman in a row if Nathalie Dechy were to beat Australian Casey Dellacqua.
The Spaniard, making her grand slam debut, was the first to hold serve in the fifth game and broke her opponent again courtesy of a Mauresmo double fault to open up a 5-2 lead and snatch the opening set in 34 minutes.
Mauresmo, who has never made it past the quarter-finals in Paris, dropped serve again in the fourth game of the second set and despite managing three games in a row, was broken again in the ninth.
The 19-year-old Suarez Navarro went on to claim victory on her first match point when Mauresmo sent a backhand long.
