Two days earlier, Nishikori, who is dealing with left knee pain, told reporters in New York that it was 50-50 whether he would participate and that he was waiting for his inflammation to subside.
The former world No. 4 returned to competition in June after undergoing hip surgery in January 2022.
Nishikori played at the ATP Tour's Atlanta Open in late July but missed three tournaments he had planned to compete in ahead of the U.S. Open beginning Monday.
The 33-year-old was hoping to make his first Grand Slam appearance since the 2021 U.S. Open.
