Novak Djokovic will have to get used to being the "bad guy" following his disqualification from the US Open for striking a line judge with a ball, American great John McEnroe has said.

The world number one was defaulted at 5-6 down in the first set of his match against Pablo Carreno Busta on Sunday after a ball he swiped in frustration hit a female official in the throat.

The 33-year-old Serbian posted an apology on Instagram, vowing to take away valuable lessons that would aid his "growth and evolution as a player and human being."
