US Open Statement from US Open Tournament Referee
on the Nick Kyrgios vs. Pierre-Hugues Herbert Match
After the third game of the second set in the Kyrgios-Herbert match on Court 17, with Kyrgios down 0-3, Chair Umpire Mohamed Lahyani, left his chair to check on the condition of Nick Kyrgios. He came out of the chair because of the noise level in the Stadium during the changeover to make sure he could communicate effectively with Kyrgios.
Lahyani was concerned that Kyrgios might need medical attention. Lahyani told Kyrgios that if he was feeling ill, that the tournament could provide medical help. He also informed Kyrgios that if his seeming lack of interest in the match continued, that as the chair umpire, he would need to take action. He again suggested to Kyrgios that he could receive medical attention.
At the next changeover, Kyrgios down 1-4, received treatment from the physio.
