Jeff Lloyd's bid for a record total of winners in Brisbane has been stalled by a suspension for his ride on beaten Golden Slipper favourite Houtzen.
Lloyd's ban is set to start on Thursday and he will miss the next two Saturday meetings.
Brisbane's premier jockey, Lloyd has ridden 100 winners this season and is closing in on Chris Munce's record of 103.
Tye Angland was also outed for the same period after pleading guilty to shifting out before straightening for home on Singe Bullet in the Slipper, causing Diamond Tathagata to lose his position.
Angland will miss the next two Saturdays - the BMW meeting at Rosehill and the opening day of The Championships at Randwick.
Josh Parr was another rider who fell foul of stewards with a three-meeting ban for careless riding at the 1100m mark of the Provincial Championships Qualifier aboard Machinegun Jubs.
Parr will begin his ban on Friday and will miss next Saturday's Rosehill meeting but will be back in time for the opening day of The Championships the following weekend.
Kerrin McEvoy will miss the BMW meeting after he was found guilty of careless riding in The Galaxy which he won on Russion Revolution.
