Nathan Aspinall is facing a fine after Sky Sports were forced to apologise when he was caught on camera making a lewd gesture.
The Asp reached the Cazoo Grand Slam of Darts with a comfortable 10-6 win against Jermaine Wattimena at the Aldersley Sports Village in Wolverhampton.
But during a break, as he followed the Dutchman off stage, the world No.12 appeared to be making a crude hand gesture – in good humour - behind Wattimena's back.
