LONDON -- Laura Robson of Britain will play singles at the Olympics, replacing Petra Martic of Croatia after she pulled out because of injury.
Robson, who is also playing doubles, will face Lucie Safarova of the Czech Republic in the first round.
The International Tennis Federation said Friday that any replacements in the draw must now come from athletes already taking part in the Games.
