Norway's Casper Ruud has pulled out of Wimbledon as he is still struggling to recover from a knee injury, his management told local media on Saturday.
The world No 16 and two-time French Open finalist suffered a shock second-round exit at the claycourt major last month, losing to unseeded Nuno Borges of Portugal.
Afterwards he said he had been struggling with a knee injury for some time and he has not been in action on the men's tour since, withdrawing from the grasscourt event in Mallorca.
"He's back on the court, and things are going well, but it looks like playing best-of-five sets is unfortunately a bit too soon. Gstaad will be next for Casper now," manager Tina Falster told NTB.
Ruud's best showing at Wimbledon is three second-round appearances.
Wimbledon starts on 30 June, while the Swiss Open in Gstaad begins on 14 July.
