Andy Murray was forced to pull out of his Canadian Open match against Italian Jannick Sinner with stomach pains.
He was due to face Scott Sinner in the last 16 in Toronto, but decided to withdraw from the tournament.
In a statement, Murray said: „I had a similar problem in Stuttgart before Wimbledon last year, which meant I missed the Queen’s Club match so I was able to play Wimbledon.
“It took about 10 to 12 days before I felt better again.
„It’s not that bad, but the risk if you play competitively is to make it worse.
„So I’ll just have to see how it develops in the coming days and hopefully get better in a few days. I’m so sorry. Thank you.”
Murray came back from 4-2 down in the third set to win 7-5, showing his usual flair and determination to see off the world number 78.
However, as his preparations for the US Open took off, the familiar injury has proved to be the former world No.1’s downfall.
The 36-year-old enjoyed his best form in the ATP rankings live on court, moving up to No. 36 – his highest since finishing No. 29 in April 2018.
Murray still plans to compete in the fourth and final Grand Slam of the year, which begins in New York on August 28.
Meanwhile, world No. 8 Pavi now faces Gael Monfils in the quarter-finals after overcoming Frenchman Aleksandar Vukic.
