His prospects for Flushing Meadows had looked positive when he travelled to NY last weekend but, after a week of practice, Murray decided the hip was simply too painful.
The men's draw at this year's U.S. Open suffered another blow Saturday when No. 2 seed Andy Murray announced his withdrawal from the tournament due to a hip injury.
British number one Andy Murray has withdrawn from next week's US Open in NY due to a persistent hip injury.
"Was actually practicing okay the last few days, but it's too sore for me to win the tournament and ultimately that's what I was here to try and do". Marin Cilic moves into Murray's spot at the bottom of the bracket, Sam Querrey slides into Cilic's former position, Kohlschreiber becomes the No. 33 seed to take Querrey's place, and Lukas Lacko gains a lucky-loser entry and assumes Kohlschreiber's spot in the bracket.
The athlete has spent the past few days practicing in NY to regain his fitness.
The 30-year-old must now decide what to do moving forward and whether to follow Novak Djokovic, Stan Wawrinka and Kei Nishikori, who have all brought their seasons to an early end because of injury.
It is unclear whether Murray will return to the court for the rest of the season.
Hip problems are also notoriously hard to overcome and there is no guarantee that keyhole surgery would significantly improve the problem, while a more serious operation would mean the end of his career.
The way the draw shook out, Roger Federer as the No. 3 seed has a 50-50 chance of either being in Rafael Nadal's half, or Murray's half. I'm sure he'll take on board all the pieces of advice he's had and make a decision that's best for him.
"If I get myself fit and healthy, there is no reason why I can't", Murray said. "But I think Andy will still play for a few more years".
Murray had avoided most of the biggest dangers in his quarter, opening against the world No104 Tennys Sandgren and with No8 seed, Jo-Wilfried Tsonga, his highest ranked opponent.
"I have been practising here and been competitive in practice when I'm not moving close to how I can when I'm healthy".
"This is actually why I didn't want to come in here".
