Former AFL player Rhys Palmer has been involved in a serious motorcycle incident, as reported by The Herald Sun's Jay Clark.

The 30-year old underwent emergency surgery in a Perth hospital and is in a stable condition.

The ex-Docker, Giant and Blue was set to suit up for the WAFL's Swan Districts this year.

“The health and wellbeing of Rhys and his passenger is of utmost importance to the club. There is no consideration of anything else of at this point in time,” Swan Districts chief executive Jeff Dennis told The Herald Sun.

“The thoughts of everyone at the club are with both of them and their families at this very difficult time”.

The accident comes 24 hours after Palmer received a life ban from racetracks for throwing a shoe onto a track at Gloucester Park.

Palmer took to Twitter to apologise for the mishap.

“Firstly, let me be clear, no shoe was deliberately thrown at a horse during any race, and I have the utmost respect for the racing community and all those involved,” the post read.

“It was simply unfortunate timing.

“I was having a light hearted wrestle with a young teammate, oblivious to what was happening around us.

“What transpired was a shoe being thrown which unbeknown to us was unfortunately at the same time the horses had made their way around the course.”
