The frustrated 24-year-old shook hands with his opponent and the umpire before he strode off the court, effectively defaulting himself from the contest.
Nick Kyrgios was defaulted from his second round Italian Open clash against Norway's Casper Ruud on Thursday after the hot-headed Australian hurled a chair on to the court.
World No 36 Kyrgios was given a code violation for 'unsportsmanlike conduct' after being broken early in the third set. Having already been handed a code violation earlier in the match, the latest outburst meant the umpire also handed him a game penalty.
This prompted an angry Kyrgios to slam his racket into the ground, kick a water bottle before he tossed a chair towards the centre of the court.
