Novak Djokovic is sensationally out of the US Open after he inadvertently hit a ball at line judge during his match with Pablo Carreno Busta.
After being broken Carreno Busta to fall 6-5 down, Djokovic reacted in frustration by hitting the ball towards the back of the court.
But the ball hit the linesperson in the throat and she collapsed to the floor.
After a prolonged chat with tournament officials, Djokovic was defaulted.
Speaking on Amazon Prime Tim Henman said: “No doubt it is right decision.
“It happened to me in 1995. We were up two sets in the doubles. I hit a ball-girl in the ear.
“Djokovic was not aiming for the line judge, but you have to be responsible for your actions.
“There is no other result but to be defaulted.”
Djokovic’s stunning exit means there will be a new men’s Grand Slam champion.
The Grand Slam rulebook states: “Players shall not at nay time physcially abuse any official opponent, spectator or other person within the precincts of the tournament site.
“Violation of the section shall subject a player to a fine up to $20,000 for each violation.
“In addition, if such violation occurs during a match (including the warm-up), the player shall be penalised in accordance with the point penaly schedule hereinafter set forth.”
Carreno Busta will now face either Denis Shapovalov or David Goffin in the quarter-finals.
