Top seed Novak Djokovic has been defaulted from his US Open fourth-round match after accidentally hitting a ball at a line judge.

Djokovic showed his frustration after losing serve to trail 6-5 against Spain’s Pablo Carreno Busta.

The Serbian world number one took a ball out of his pocket and hit it behind him, striking the female line judge in her throat.

After a lengthy discussion, he was defaulted by tournament officials.

Djokovic was the heavy favourite to win the men’s singles title at the US Open, which is being played behind closed doors and is the first Grand Slam to take place since the beginning of the coronavirus pandemic.

Going into the match against 20th seed Carreno Busta, Djokovic had not lost a singles match in 2020.

The 33-year-old was aiming for an 18th Grand Slam triumph to move closer to rivals Rafael Nadal and Roger Federer, who are not playing in New York, in the race to finish with the most men’s major titles of all-time.
