Ronnie O'Sullivan misses black at UK Snooker Championship
Reigning world champion Ronnie O'Sullivan fails to make contact with a decisive black at the UK Championships, handing Marcus Campbell the second frame of their third-round match.
The miss - from under an inch away - came at the end of an extended period of safety play at the Barbican in York.
BBC experts Stephen Hendry and John Parrott struggled to make sense of the error, but O'Sullivan recovered to win 6-2 and seal a place in the fourth round against Robert Milkins.
