Laura Robson has played down concern over an injury that has forced her to withdraw from an ITF event in Canada.

The former British number one recently returned from a prolonged absence that was caused by a wrist injury, with the left-hander securing her first win since her comeback in Granby last week.

However, the 21-year-old was forced to bring an abrupt halt to her first-round match on Tuesday when trailing 5-1 to Barbora Stefkova, leading to fears that she had sustained another problem with her wrist.

The problem has been played down, though, with the Olympic silver medallist revealing that she suffered a stomach strain during the warm-up.

Robson will aim to recover in time for the US Open, which begins in New York on August 31.
