Stan Wawrinka has withdrawn from two upcoming ATP World Tour Masters 1000 tournament – the Coupe Rogers in Montreal and the Western & Southern Open in Cincinnati – due to a knee injury.
“After much consideration and consultation with my doctors and my team, I have decided to skip Canada and Cincinnati to be on the safe side, although I’ve been battling hard to be fit for these events,” said Wawrinka.
“It’s hugely disappointing for my fans and for myself that I have to make this decision. But I need to be 100 per cent confident before I resume competition that the injury that has plagued at Wimbledon has been resolved. My team and I are doing everything to make this a speedy recovery.”
Wawrinka, who is currently No. 4 in the Emirates ATP Rankings, struggled with knee problems during the grass-court swing at the Aegon Championship and Wimbledon.
The 32-year-old Swiss has a 26-11 match record on the season, including one ATP World Tour title at the Banque Eric Sturdza Geneva Open.
