Leading jockey Dwayne Dunn has been suspended for causing interference in the Tattersall's Tiara at Eagle Farm today.

Dunn, who rode the unplaced Shopaholic in the feature race, pleaded guilty to causing interference to Alltherightmoves (Jason Taylor) at the 800m.

Stewards told Dunn, who has had an umblemished record in the past year, the interference was not at the high end of the scale but a suspension was warranted because it was a Group One event.

Dunn's suspension will start after he rides at Flemington next Sunday. He will be back in action on July 14.
