Czech Vondrousova withdrew from the Games due to a hand injury, saying her focus was on being ready for the year's final Grand Slam, which starts on August 26th in New York.
Norrie, whose best US Open result came in 2022 when he reached the fourth round, pulled out of the Olympics due to a forearm injury.
"I'll take some rest and recharge," Norrie wrote on Instagram. "Can't wait to get back competing like a dog."
