Britons Johanna Konta and Dan Evans will play their US Open second-round matches on Thursday after rain forced the cancellation of Wednesday's schedule on the outside courts.
After a six-and-a-half-hour delay, British number one Konta and Margarita Gasparyan began their warm-up at 22:30 BST but the rain then came down again.
They will now play on court five on Thursday from approximately 18:00 BST.
Evans will play world number 27 Lucas Pouille first on court 12 from 16:00.
The winner of that match would then have to face third seed and five-time champion Roger Federer in the third round on Friday.
All Wednesday's day matches on the covered show courts were completed with Federer coming from a set down to beat Bosnian Damir Dzumhur 3-6 6-2 6-3 6-4.
The night matches involving defending men's champion Novak Djokovic, six-time women's champion Serena Williams and French Open winner Ashleigh Barty were due to be played from 00:00 BST.

In Thursday's show court schedule, German sixth seed Alexander Zverev opens play on Arthur Ashe Stadium at 17:00 BST against American Frances Tiafoe, before Wimbledon champion Simona Halep takes on another American, Taylor Townsend.
On Louis Armstrong Stadium, Czech sixth seed Petra Kvitova faces Germany's Andrea Petkovic from 16:00, followed by defending champion and top seed Naomi Osaka who plays Poland's Magda Linette.
In the Arthur Ashe night session, Spanish second seed Rafael Nadal takes on Australia's Thanasi Kokkinakis after Danish 19th seed Caroline Wozniacki, twice a finalist at the US Open, plays Australian Open semi-finalist Danielle Collins.
Coco Gauff, the American 15-year-old who reached the second week at Wimbledon, plays Hungary's Timea Babos from 00:00 on Louis Armstrong Stadium.
In the men's doubles, Jamie Murray and fellow Briton Neal Skupski open their campaign against Americans Nathaniel Lammons and Robert Galloway, third on court 12.
