Nick Hall will miss the Group One ride on favourite Azkadellia in the Doomben 10,000 because of suspension with Mark Zahra to take his place.
Hall was outed for high-range careless riding at Ballarat on Wednesday, a day after he returned from a similar ban.
Azkadellia's trainer Ciaron Maher said on Twitter, Zahra would ride the mare at Doomben on Saturday week.
She is the early $3.50 favourite for the sprint ahead of Delectation and Ghisoni at $7.
Hall's suspension begins after Saturday when he rides Churchill Dancer in the Group One Goodwood in Adelaide.
He returns on June 4, the day of the Queensland Oaks meeting in Brisbane.
