Damian Steiner, the chair umpire who officiated the 2019 Wimbledon final between Roger Federer and Novak Djokovic, has been fired for giving "more than a dozen" interviews without ATP's (men's tennis governing body) authorisation. The interview contents of the gold-badge umpire also violated the standard protocol, said ATP. French umpire, Renaud Lichtenstein replaced Steiner in 2019 US Open.
