Serena Williams was forced to pull out ahead of her second-round match against Tsvetana Pironkova.
The 23-time grand slam champion came into the tournament nursing an Achilles injury she picked up during her semi-final defeat at the US Open earlier this month.
Meanwhile, 12-time champion Rafael Nadal laid down a marker with a thumping 6-1 6-0 6-3 win over Mackenzie McDonald.
Here, the PA news agency looks back at day four at the French Open.
