Jockey Josh Cartwright has been handed a 18-month suspension after his infamous ride at Morphettville last month.
He has also had his trainer's license suspended for six months.
Thoroughbred Racing South Australia stewards described the reckless riding as "the worst [they had] ever seen in Australia".
Stewards said there was no evidence Cartwright's decision to ride Senior Council towards swooping rival runners was related to betting.
Cartwright's girlfriend Anna Jordsin won the race.
