A South Australian jockey has been stood down from riding after cutting in front of other riders in an alleged bid to let his girlfriend win the race.

Josh Cartwright has been stood down from riding pending the determination of a penalty for reckless riding at Morphettville - a race won by his longterm Anna Jordsjo, Daily Mail Australia reports.

Cartwright pleaded guilty to the serious charge in the final race on Saturday when he shifted out in the straight and cannoned in to another horse which in turn made heavy contact with the horse to the outside.

Jason Holder, rider of the second affected horse, almost came off but managed to regather and stay on his mount.


SA stewards found Cartwright had directed Go The Journey outwards at an acute angle in a reckless manner around the 200m mark.

At the time on the incident Jordsjo was leading the race on $4 favourite Murti and went onto win the 1250-metre race.

Stewards opted to adjourn the inquiry to consider what penalty should apply.

The stewards also stood Cartwright down from all riding including trackwork.

Cartwright holds a dual licence and is scheduled to have his first runner as a trainer in the next few weeks.

In October, Damien Oliver missed several key spring carnival meetings when he became the first Victorian jockey in a decade found guilty of reckless riding and was given a 20-meeting suspension.

In 2015, Brisbane jockey Luke Tarrant was outed for six weeks, reduced to four weeks on appeal, on a reckless riding charge from the Group Three Grand Prix Stakes.
