Washington - Three-time Grand Slam champion Andy Murray said on Friday he will return to singles competition next week at the ATP Cincinnati Masters, seven months after having right hip surgery he feared might end his career.

The British star posted a photo of himself on his Facebook page on court while yelling with a clenched right fist and the caption: "That feeling when you accept a wildcard for the singles in Cinci... #LetsDoThis #HereWeGo."

The 32-year-old Scotsman has fallen to 325th in the world rankings after his January operation to ease nagging hip pain.

His first match next week in Cincinnati in the final major tuneup for the US Open will be his first competitive singles outing since the Australian Open in January.

Murray has played doubles in recent weeks while practicing his singles in a bid to regain his fitness in time to play at Cincinnati as preparation for this year's final Grand Slam event that starts in New York on August 26.

Murray and his brother Jamie played doubles together for the first time since the 2016 Rio Olympics in Washington last week, losing in the quarter-finals.

Murray, the 2012 and 2016 Olympic singles champion, won Grand Slam singles titles at the 2012 US Open and Wimbledon in 2013 and 2016.
