Reigning champion Rafael Nadal will miss the US Open later this month due to a right wrist injury.

"I am very sorry to announce I won't be able to play at this year's US Open, a tournament in which I've played three consecutive finals in my last participations," he wrote on his official Facebook page.

The 14-time Grand Slam champion has not played since suffering a shock defeat to 19-year-old Australian Nick Kyrgios in the last 16 at Wimbledon in July.
