The ignominy of being suspended for causing his own fall might turn out to be nothing compared to the pain Jason Collett could feel at the business-end of the Sydney carnival.

Collett's Epsom Handicap day book of rides was full of Group One promise until he was banned for 10 meetings after coming to grief from his mount during the last race at the two-day Newcastle Gold Cup carnival.

In the race before, the former New Zealander celebrated one of his biggest wins when he rode Disclaimer to victory in the Cup.

The suspension will cost him the chance to keep an association with Disclaimer in the Group One Metropolitan.

And in all likelihood the ride on Chris Waller's top filly Winx in the Group One Flight Stakes has also gone begging.

Then there's all the manoeuvring behind the scenes to position himself for the Epsom Handicap and the first Sydney two-year-old races of the season.

"I was hoping to pick up a lightweight Epsom ride and I've been doing a fair bit of work on some two-year-olds going to the Breeders' Plate and Gimcrack Stakes," Collett said.

Losing the ride on Winx could hurt most of all as Collett chases a Group One breakthrough.

Winx is favourite to make it back-to-back black type wins in the Tea Rose Stakes at Randwick tomorrow.

"If things go well in the Tea Rose then you'd think I would have stayed on her," Collett said.

Collett's Randwick book also includes Moriarty in the Hill Stakes and Didntcostalot in The Shorts.

He will finish his suspension in time to return to riding at the Group One Spring Champion Stakes meeting at Randwick on October 11.
