Nick Kyrgios pulls out of singles in Atlanta with knee problem
The 27-year-old was drawn to take on German Peter Gojowczyk in his opening round of the ATP 250 hardcourt event in Georgia but instead addressed the crowd after his withdrawal. "First of all, I just want to say I'm extremely shattered that I'm not able to compete tonight," Kyrgios, who lost to Novak Djokovic in the Wimbledon final, said on court.
