Umpire James Keothavong didn't expect to be hit in the head as he umpired the Australian open clash between Victor Troicki and Nick Kyrgios.
The Serbian, Troicki, tried to return a serve from world number seventeen Nick Kyrgios when he blasted his backhand high and wide towards the umpire's head.
Troicki ran straight over to him in a very apologetic manner and luckily the British umpire reacted to the situation in a humorous way as he laughed it off.
The former top 15 player, Troicki, was trailing by two sets and 4-1 down in the third set tie-break when this hilarious moment occurred which put a rare smile on the Serbian's face.
A large shriek was let out by the crowd when the ball struck off Keothavong's head but it all soon calmed down as the excellent Kyrgios wrapped up the tie-break to seal a straight sets victory.
The young, vibrant Australian progresses through to the last 32 to face world number 15 Jo-Wilfried Tsonga.
There haven't been any major shocks in the Australian Open yet as top seeds Rafael Nadal, Roger Federer and Grigor Dimitrov all remain in the competition.
Also, six-time champion Novak Djokovic won comfortably against Donald Young on his return to major tournament tennis.
However, it was this comical moment in the Troicki vs Kyrgios match that will be one of the main talking points in the second round, despite a routine straight-sets victory for the Aussie.
