Penrith forward Isaah Yeo has been sidelined with a shoulder injury, and will miss the remainder of the 2019 season.
Yeo suffered a shoulder injury back in round eight, and decided to delay surgery in the hope of a late-season return after rehab.
He returned to the field soon after with the Panthers short on numbers, and had played 11 straight games after the initial injury.
However, after suffering a shoulder dislocation again on Friday night, Yeo has undergone surgery which has ended his campaign.
The Panthers hope the 24-year-old will be fit for the start of next season.
