Jarryn Geary has undergone surgery this afternoon to repair his injured right shoulder.

The 32-year-old left the field late in the Saints game against Sydney in Round 12 with a serious dislocation.

After a short trip to hospital to set the joint back in place, Geary commenced his recovery, with surgery becoming the clear option soon after.

"Following consultation with our medical team and specialists it became obvious this was the most appropriate course of action," Chief Operating Officer Simon Lethlean said.

"While it’s never good to have Jarryn on the sidelines, we know this won’t limit his influence on the group and that he’ll provide a great example of how to tackle recovery, as he has shown time and time again."
