The left-handed opener has become the first Test player in history to be dismissed for a golden duck in his 100th Test appearance. When he started this match, he broke Sachin Tendulkar's record of becoming the youngest player in 100-Test club but now he has another record which he would have been happy without.
England, who were set a target of 504 to win the third Ashes Test against Australia, lost their skipper off the first ball. Cook was bowled by paceman Ryan Harris.
In his 99 previous Tests, Cook was never out off the first ball. But, in his milestone Test, in the second innings, he collected his first ever golden duck and also the ignominy of the first batsman in history.
In the first innings, Cook had made 72. Australia captain Michael Clarke is also playing his 100th Test in this match.
Australia hold a 2-0 lead in the five-match series.
