Storm's King cops $5,000 fine

Melbourne centre Matt King has been slugged with a $5,000 fine for publicly ridiculing Grand Final referee Paul Simpkins.

Addressing a contingent of Storm supporters as part of the club's fan day on Monday, King called Simpkins a "dickhead" following the whistleblower's handling of the controversial 15-8 premiership victory by Brisbane.

Simpkins was involved in a series of contentious decisions, most notably his decision not to call an obstruction play on Clive Churchill medallist Shaun Berrigan.
