Ding Junhui overcame the embarrassment of missing out on a maximum break after forgetting he was on track for a 147 to book his place in the second round of the World Snooker Championship.
China's Ding was trailing opponent Mark Davis 5-3 at the Crucible and was at the table on a break of 96 when he inexplicably screwed back for the blue ball instead of playing for the black.
The apparent lapse in concentration left the audience stunned, while Ding covered his head in his hands then proceeded to smile after realising his error.
Following his mistake, Ding regained his composure and went on to claim a 10-7 win over Davis.
