Billy Bowden (left) stretches his arm to indicate that Michael Beer, rather than celebrating a maiden Test wicket, has to bowl again on in Sydney.
After overstepping, he had had Cook caught out, but the umpire's call offered Cook a reprieve which he would go on to take advantage of on his way to 61 not out.
Beer, making his Test debut as the tenth slow bowler playing Test cricket for Australia since the retirement of Shane Warne in 2007, went wicketless for the rest of the day.
