Experienced referee Jan Verhaas had a moment to forget during Ronnie O’Sullivan’s match against Pang Junxu at the World Snooker Championship.
The bizarre incident took place in Sunday’s afternoon session, with the Rocket enjoying a 10-4 lead over his Chinese rival. He got off to a strong start, making a couple of century breaks to extend his advantage from the previous day.

In the early stages of the 15th frame, Pang was at the table and found some joy with many of the reds scattered across the baize. At one point, he nailed the pink into the right middle pocket but was forced to wait for his next shot following a mistake from Verhaas. He respotted the pink in the wrong place, seemingly confused by another light-coloured dot on the table.
