Milos Raonic has become the latest top tennis player to pull out of the US Open, saying he had a procedure on his left wrist.
The 11th-ranked Canadian, the runner-up at Wimbledon last year, announced his withdrawal from this season's last Grand Slam tournament on Instagram on Wednesday night.
Raonic says he had "portions of the bone that have been causing the discomfort" removed Wednesday.
The US Open starts from Monday.
Raonic joins 12-time major champion Novak Djokovic, 2016 US Open champion Stan Wawrinka and 2014 finalist Kei Nishikori in missing the tournament because of injuries.
Also sitting out the action at Flushing Meadows: 23-time major champion Serena Williams, who is pregnant, and two-time Australian Open winner Victoria Azarenka, who is dealing with a custody case involving her baby son.
