ESSENDON star Courtenay Dempsey has been banned from contesting the Gatorade Bolt - with the AFL threatening to fine him $20,000 if he takes the track.

The Daily Telegraph can reveal Dempsey - who has been training for a fortnight -

has been told not to compete in an event including NRL stars Jarryd Hayne and Greg Inglis and Wallaby Lachie Turner.

The Bombers flyer, who has been in Sydney for the past two days preparing for the event, is said to be devastated by the instruction from the AFL.

The Daily Telegraph has contacted the AFL and is awaiting a response.

Courtenay's agent Shane Casley confrimed there were a number of issues surrounding his client's inclusion in the race.

"There's lots of issues surrounding this and we've decided that it's better that Courtenay doesn't run," Casley said.
