Shaun Murphy has lashed out at a spectator on social media following an incident during his World Championship opener at the Crucible.
The 43-year-old took to Instagram to address a front-row fan who audibly criticised one of his shots during Monday's first-round clash with Fan Zhengyi.
"If you're sat on the front row in the Crucible and I play a shot that may not work for a particular reason, it's probably best not to say 's**t shot' out loud," the 2005 champion wrote. "I've got ears."
Murphy added with dark humour: "I missed my next shot as I was contemplating which end of my cue to nut him with."
