US Open Statement on Chair Umpire Mohamed Lahyani:
After a comprehensive review conducted by US Open officials, including US Open Tournament Director David Brewer, Tournament Referee Brian Earley and others, the US Open determined that chair umpire Mohamed Lahyani’s conduct during Thursday’s second-round match involving Nick Kyrgios and Pierre-Hugues Herbert went beyond protocol. Lahyani was advised to adhere to proper protocols in all matches that he officiates moving forward.
Lahyani will continue to officiate during the 2018 US Open. His performance will continue to be evaluated, as will that of all chair umpires throughout the course of the US Open.
