Novak Djokovic declined to do a customary postmatch TV interview at the Australian Open after his win Sunday night to protest comments made on air by someone who works for the official broadcaster of the tournament in the host country.

Carlos Alcaraz and Novak Djokovic have set up a quarterfinal showdown at the Australian Open. Tuesday's contest will be their eighth head-to-head matchup, but their first at Melbourne Park and their first that is neither a semifinal nor a final.

Novak Djokovic has put himself at loggerheads with the Australian Open’s host broadcaster by refusing to give any more on-court interviews until he receives an apology from anchorman Tony Jones.
