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.

The 24-time Grand Slam champion opted out of a traditional on-court interview Sunday following his fourth-round win over Czechia’s Jiri Lehecka at the Australian Open, citing “insulting and offensive comments” made toward him by a presenter for Channel 9, which broadcasts the tournament, days prior.
