Snooker star Yan Bingtao has been slammed for breaking an "unwritten rule" of the sport on the way to victory over Mark Selby.
The Chinese potter overcame the Jester from Leicester to win 13-10 after a marathon final session which produced the longest frame in Crucible history. The pair battled for 85 minutes and 22 seconds before Yan eventually ended he stand-off, eventually going on to seal the tie.
