Andy Murray moved into the main draw of the U.S. Open when Alexei Popyrin of Australia withdrew from the tournament on Sunday.
Murray previously was set to receive a wild-card entry. American Mitchell Krueger will now land that wild-card invitation.
Murray, the 2012 U.S. Open champion, is returning from a hip injury.
A three-time Gland Slam winner and a two-time Olympic gold medalist, Murray last played in a Grand Slam event in the 2019 Australian Open. The 33-year-old Brit has struggled with hip and pelvic injuries since then and underwent hip surgery.
Murray is ranked No. 129 in the world, which was one place out of earning a direct entry into the event.
Murray is one of just three men -- Novak Djokovic and Marin Cilic are the others -- in the field to have won a Grand Slam singles title. Rafael Nadal opted out over concerns of traveling during the coronavirus pandemic, while Roger Federer is out with a knee injury. This is the first time since 1999 that neither Nadal nor Federer have played in the U.S. Open.
The 21-year-old Popyrin is ranked 103rd in the world. He joins fellow Aussies Ashleigh Barty (women's No. 1 in the world) and Nick Kyrgios (men's No. 40) in dropping out of the U.S. Open.
Two other highly ranked women, No. 5 Elina Svitolina of Ukraine and No. 7 Kiki Bertens of Netherlands also withdrew.
Krueger is ranked 195th in the world.
The U.S. Open is slated to begin Aug. 31.
