London - France's Michael Llodra retired from his second round Wimbledon match with Italian 23rd seed Andreas Seppi on Thursday, taking the total of pullouts to 11 at the tournament.
Llodra had just dropped the first set 7-5 to Seppi when he called the doctor on to Court 14.
But he opted not to carry on allowing Seppi to book a third round clash against Japan's Kei Nishikori.
He was joined by another Frenchman, Paul-Henri Mathieu, who quit while trailing 6-3, 5-1 against Feliciano Lopez of Spain.
Llodra and Mathieu joined seven players who pulled out Wednesday.
Nine men and women withdrew or stopped mid-match during the first round of the 2011 U.S. Open.
All told, 12 players have pulled out of Wimbledon so far, one short of the full tournament record, set in 2008.
