Jason Collet will miss Stradbroke Handicap day in Brisbane because of a suspension which soured his treble at Randwick.

Jockey Jason Collett's winning treble at Randwick has been tempered by a suspension which rules him out of Brisbane's premier race day.

Collett rode three winners for trainer Chris Waller on Saturday including the Queensland Derby favourite Nobu but was outed for his ride on odds-on favourite Reloaded who finished second to Prince Fawaz in the two-year-old handicap.

Prince Fawaz has now displaced Reloaded as favourite for the J J Atkins on June 8 at Eagle Farm.

The day features three Group One races - the Stradbroke Handicap, the Derby and the J J Atkins.

Collett pleaded guilty to shifting out on Reloaded near the home turn, bumping Floreat Pica who in turn was taken out onto Sea Of Life who had to be steadied with Prince Fawaz at the end of the chain reaction.

He will be out from June 2 to 13.
