English Umpire Richard Kettle borough got injured

It is unusual to hear that umpire got injured as they just stand on the pitch and indicate the players. This event happened in the fourth fixture between India and Australia. It was the first inning when Australia had just started their batting. In the fifth over of Ishant Sharma, which is fast bowler, Aaron Finch played a wonderful straight drive which hit the Umpire Richard on his leg. At that time, he seemed to be ok, but later in the 17th over, he felt an unbearable pain which made him out.
