Andy Murray, the world's former number one, says he will not play a role in the US Open this month.
The 2012 champion planned to do a double in New York, but says that "the double is done for me for now."
Instead, he will play singles at the ATP event in Winston-Salem next week before considering considering participating in a Challenger Tour tournament during the US Open.
"I will not play a double at the US Open," Murray told BBC Sport.
"My goal is to get back to the level I want in the single and I've decided that I need to focus all my energy on it now," added Murray, after he and Feliciano Lopez completed the doubles had reached Cincinnati.
"The US Open, doubled and mixed, may take a few more weeks to slow things down."
Murray has taken the last wildcard for the next event in Winston-Salem, North Carolina. He will participate in the raffle with Kevin Anderson, Denis Shapovalov, Tomas Berdych and the British Dan Evans.
Most of the field is out of the top 50 in the world, and some outside the top 100, but Murray says he would have entered the qualifying tournament if he had lost the doubles on Thursday in Cincinnati.
"Because I want matches and that's what I need right now," said Murray, who had to undergo a career-preserving hip replacement in January.
"I do not feel like I have to play the main draw at every single tour event, I've barely played in recent years, and after talking to my team about it, I think the doubles for me after this week done is for the time being.
"I have to concentrate on playing games in the single-seat and there are not many tournaments by the end of the year."
At the end of his week in Winston-Salem, Murray will decide if he wants to compete in a Challenger event during the US Open, which begins on August 26th.
"It depends on how Winston-Salem is doing," he said.
"The feeling I have had since my singles [his first for seven months, against Richard Gasquet in Cincinnati] That was that I played decently, but physically I want to play games by the end of the year, so I feel ready for the beginning of next year.
"Well, if I do well in Winston-Salem, I know my level is good enough and I'm ready to win tournaments on a tour level, but if not, it makes sense to lower one level and maybe a few smaller ones To play tournaments. "
The obvious event for Murray would be the Challenger in New Haven in the second week of the US Open. The field there should be very strong, as many who lose in the first week in New York, will opt for a competition.
Murray's other option is to return to the practice site. However, given the amount of training and rehab that he has performed in recent years, this is not a particularly attractive proposition.
Towards the end of September, Murray will travel to China, where he will play in Zhuhai and Beijing.
The next week's Shanghai Masters is another option, after which Murray hopes to play "three or four events" in Europe before the year ends.
