The presenter at the center of Novak Djokovic’s decision to boycott on-court interviews at the Australian Open has apologized to the 24-time Grand Slam champion, saying that he “overstepped the mark.” Channel 9 presenter Tony Jones was overlooking a group of Serbian fans while recording a dispatch from Melbourne Park Friday night.

Novak Djokovic declined a post-match TV interview after winning in the fourth round of the Australian Open after an on-air personality from the local Australian broadcaster of the tournament made negative comments about him in front of Serbian fans.

Veteran Nine sports reporter Tony Jones has apologised on air to Novak Djokovic for “any disrespect” implied by his comments mocking fans of the Australian Open champion, as the Serbian Council of Australia lodged a human rights complaint and called for Jones to be fired.
